It is attractive for private construction in that it provides excellent thermal insulation with low weight and at the same time has significant vapor permeability - it “breathes”. However, these same are also the cause of a number of features of the material.
Peculiarities
The best and unrivaled material for a bath is, of course, wood. Any other options are its substitutes, which lack some properties. Arbolit is no exception.
Wood concrete consists of 75% wood and due to this, its qualities are to some extent close to those of . In any case, this material is clearly better than brick or ordinary. The fact is that if the temperature in the dwelling is maintained constant, then the bath is a room where the fastest possible heating is expected, but only periodically.
Therefore, it acts best material wood: provides fast heating, good thermal insulation and at the same time outputs excess moisture out of the bath. The walls in a wooden bathhouse never "cry".
Arbolite does not have the last property. The chips in it are crushed to such a state that the difference in the direction of the fibers does not matter. Therefore, wood concrete should be considered not as an analogue of wood, but as a stone building material with high vapor permeability.

Sequencing
- The foundation for a bath is usually made of tape, with a mandatory plinth 50 cm above the ground.
- The laying of the walls is the most common, for a bath they suggest laying in half a block, that is, laying a “brick” on the edge.
- But when finishing the bath, they build a rather complex multi-layered “pie”. The fact is that for both the dwelling and the bath, it is important to observe the correct sequence of materials: its vapor permeability should increase from the inside to the outside.
- According to specifications for outer skin suitable only lining made of wood.
The sequence of building a bath from wood concrete with your own hands is as follows:
- The interior decoration with wood actually, there is already a violation here, since the vapor permeability of wood is, of course, higher, ventilation gap 1.5–2 cm, vapor barrier and insulation basalt wool, as it refers to non-combustible materials.
- Then a wall of wood concrete, windproof film, again a ventilation gap of 2–5 cm and an external finish.
A lot depends on the quality of the arbolite, as stated by the numerous reviews of the owners of arbolite baths on the forums.
- If structural wood concrete with great content cement, then you can’t do without vapor barrier and basalt insulation: the material is much closer in properties to sawdust concrete, and such a bath will warm up for a long time.
- If heat-insulating with a large amount of wood chips is used, then the insulation layer can be omitted.
Compliance with fire safety rules in such a bath is no different from a brick one, since wood concrete, unlike wood, is completely non-combustible.
How to make a garage from wood concrete with your own hands, read below.
The owner of such a building will tell about the features of building a bath from wood concrete in this video:
Garage
For the most part, the garage does not apply to rooms that are heated in winter: a car can be seriously damaged by a large difference between the temperature in the garage and the temperature in the air. However, some kind of insulation is necessary to ensure minimal comfort for the owner of the box. Wood concrete is perfect for this role: reviews of garages made of wood concrete blocks are in most cases positive.
- The foundation is constructed light, as a rule, tape. In most cases, they do without a base.
- The laying of the walls is ordinary, with dressing. For masonry, either perlite mortar is used. Since the height of the garage does not exceed 2.5 m, reinforcement is not necessary. You can use plastic reinforcing mesh to give the building a neater look.
- Since there are no ceilings in the garage, the reinforcing belt in the upper part of the walls is not arranged. Are used wooden beams or steel trusses. Roof - corrugated board.
- Arbolit perfectly holds fasteners, so it is easy to install the gate frame. Any racks and shelves are also not a problem.
- For reliability, the garage can be finished with plaster, especially when it comes to a rainy region.
Highly great importance for the durability of the structure, it has the quality of the material: undried wood concrete, including foreign objects, shrinks, creates difficulties in laying and wears out much faster. Judging by the reviews, this issue is a stumbling block when choosing a material for a garage.
The use of wood concrete in construction
It is undesirable to use wood concrete, even structural for more than 3 floors. In this case, a serious strengthening of the structure will be required. steel reinforcement, and the latter, as you know, creates cold bridges. For a 2–3-story building, a conventional reinforcing mesh is sufficient.
About how to line the walls of wood concrete, how thick they should be, how to make them with your own hands, read on.
Walls
Arbolit different types used in the construction of different walls:
- bearing, that is, loaded - they require structural wood concrete, the thickness of such a wall is 50 cm, although in many lightweight buildings - a garage, a summer house, they are limited to 30 cm;
- self-supporting- also most often cost a thickness of 30 cm from blocks measuring 30 * 20 * 50 cm;
- partitions- internal walls are constructed with a thickness of 20 cm from blocks of 20 * 20 * 50 cm.
Blocks are laid on a cement-sand or perlite mortar. The latter is closer in terms of thermal insulation, and therefore is the best choice. For masonry, choose a slightly under-dried material or pour it abundantly with water before applying the masonry mortar: otherwise, the moisture from the solution will be in the blocks before the masonry has time to set.
According to GOST, wood concrete for building walls is produced with a finished outer finishing layer of. The inner layer may be present - plaster, may be absent. In fact, there are rarely blocks with any finished finish.
Arbolite must be protected from moisture, as the material absorbs it too well. Most often, plaster acts as a protective layer for walls made of wood concrete, since we are talking about structural material, whose vapor permeability is lower than that of thermal insulation. So there is no conflict.
The interior decoration of walls made of wood concrete has no restrictions - from tiles to wallpaper. Since the surface has high adhesion, any cladding adheres perfectly to wood concrete walls.
The following video is devoted to the construction of wood concrete walls:
floors
The floor from the wood concrete does not cause unequivocal approval, judging by the reviews. Used for this, which you have to either do it yourself or order separately from the blocks. The thickness of the screed layer, as well as the insulation layer, reaches 10–15 cm, which is not always economically profitable.
It is possible to lay wood concrete on the base of the floor or for insulation on a concrete screed.
- In the first case, a cement-sand base is prepared and very carefully: the use of vibrators is mandatory. Then reinforcement is laid - cells 25 * 25 cm, and poured with ordinary concrete. Waterproofing is carried out - or with a primer, and then a wood concrete screed is poured.
- On the concrete base the screed is laid in two layers: 7 cm from wood concrete with a high content of wood chips - heat-insulating, and the last 3 cm - from denser wood concrete.
Such a floor arrangement is possible only with high ceilings. Read more about wood concrete flooring.
overlap
For floors, special combined slabs have been developed, since the strength of wood concrete as such is clearly not enough for the product.
- The slab consists of three layers: the lower one is made of concrete grade M25 or M35 with reinforcing mesh, with a diameter of 10–12 mm. The fittings are prestressed, which significantly increases the reliability of the product. The middle layer consists of heat-insulating wood concrete, and the top layer is made of concrete of the same brand.
- There may be another option, in which the lower layer and the ends of the slab, perpendicular to the plane of the lower layer, consist of concrete. Such a plate is cheaper and prevents uneven compression of wood concrete in the second layer.
A slab up to 4.8 m long is produced. However, for private construction, judging by the reviews, 3.5 m slabs are preferable.
About whether it is possible to make a foundation for a house of wood concrete with your own hands, read below.
This video will tell you more about sawdust concrete floors:
Foundation
Arbolite is a material prone to water absorption due to its porous structure, and therefore the construction of a foundation from it is impossible. Wood concrete is defenseless against dampness and groundwater.
Wood concrete is not a well-researched material to recommend. wide application. However, there are areas where wood concrete has already earned its good reputation and can be used without fear.
Wood concrete has been used in construction for more than fifty years, and during this time it has established itself as an excellent structural and thermal insulation material for construction low-rise buildings and structures. Dachas are built from it and country houses, outbuildings. A bathhouse made of wood concrete blocks is not much inferior to a wooden building in terms of its qualities and characteristics.
Such properties of the material are provided by the components included in its composition: cement, sand, vegetable and wood fibers. Good vapor permeability, heat and sound insulation, structural strength - all these are wood concrete blocks, reviews of which by both specialists and consumers indicate its excellent technical and operational characteristics.
Technology for the production of arbolite blocks: from what components is arbolite produced?
The technology by which blocks are made from wood concrete is similar to the process for the production of wall blocks from cement-sand mortar. The difference lies in the fact that when preparing the mixture, instead of a certain part of the sand, chopped wood or vegetable fibers are used. For the preparation of the mixture, cotton, rice straw, flax and others are used. industrial crops. The finished mixture is poured into a mixer and mixed with water. Depending on the percentage of components, heat-insulating and structural blocks are distinguished. The former have a density of 400 to 500 kg/m3, while for the latter this value reaches 850 kg/m3. Strength different types blocks is also different and is M5-M15 and M25-M50, respectively.
The thermal conductivity of wood concrete depends on its density. At D400, it is 0.08 W / (m ° C) for chopped wood, and 0.07 for plant fibers. For structural blocks with a density of D700, the thermal conductivity with wood filler is 0.14 W / (m ° C), and with vegetable filler - 0.12. The lower thermal conductivity of wood concrete with fillers from plant fibers is due to the greater porosity of the feedstock.
To increase the strength in the manufacture of wood concrete blocks, reinforcement is used. It'll make it harder technological process, and increases the cost of production, but allows you to get more durable material, from which buildings with a higher height can be erected. Wherein protective layer wood concrete should be at least 15 mm. For reinforcement use bar steel classes A-I, A-II and A-III and a wire of a periodic profile.
Do-it-yourself weight, dimensions and laying walls from wood concrete blocks
Houses made of wood concrete blocks are warm and relatively inexpensive, which is important for reducing construction and operation costs. Due to its high vapor permeability, wood concrete provides moisture regulation, which helps to improve the microclimate. When choosing materials for finishing, this property must be taken into account and layers should be applied as the vapor permeability coefficient decreases.
Due to the low density and good workability of the material, the construction of wood concrete blocks requires less labor than the construction of a house made of brick, prefabricated or monolithic reinforced concrete. The first row of blocks is laid on upper part plinth or foundation. First lay out the corners and intersections of the outer and internal walls. Having laid the knots to a height of 3-4 blocks, they begin laying the rows. Each row needs careful alignment. Given the good machinability, the blocks are hewn using power tools.
In order to give the masonry greater strength, every 2-5 rows are reinforced. Additionally reinforce window and door openings, as well as the top row. Often, the masonry is completed with a reinforced concrete armored belt, which is used to mount a Mauerlat or a roofing system.
Now such an approach is being applied to construction that properties such as the minimum heat transfer coefficient of a simple installation technology are important for the materials used. This requirement is fully met by wood concrete, which is also called wood concrete. In terms of heat transfer, it lags behind wood, but not by much. But it surpasses cinder blocks and ordinary concrete with.
Wood concrete houses: main characteristics
The use of wood concrete allows construction by any modern methods:
- Combined.
- Block.
- Monolithic.
In the case of monolithic construction, the wood concrete itself is made right on the site. The block variant assumes that ready blocks. Or they are produced independently, in full.
Let's start with the shortcomings, without which no material can do:
- Rodents often prefer this material for their food, or simple grinding of their teeth. But heights ground floor enough to keep you safe.
- For the foundation you need to use heavy concrete. It is important to carry out thorough waterproofing of the base. You can not do without a concrete or brick basement, with a height of at least 50 centimeters.
- Wood concrete saves high level frost resistance only if a low level of moisture is maintained. Additional finishing is required, otherwise the penetration of moisture inside cannot be avoided.
- Arbolite cannot be used where humidity of 75 percent or higher is expected. This shortcoming is the most serious.
About the benefits
The material has much more of them:
- If blocks are used ready-made construction time is very short.
- The material is not afraid of mold along with the fungus.
- Arbolit is 85 percent of sawdust. But it still refers to non-combustible substances.
- Excellent sound insulation due to the porosity of the surface.
- The same porosity helps to improve the quality of adhesion to concrete or plaster. Which simplifies the implementation of finishing several times.
- High thermal insulation qualities. With a smaller thickness, these qualities are not inferior to those of concrete and bricks.
- The ability to resist tensile loads. Even at the beginning of shrinkage, cracks do not appear on the walls. The basics were no exception. from monolithic wood concrete.
- Light weight material. The density of the structural type variety reaches only 800 kg/cm3. Thanks to this, any building will have a small weight. It is quite possible to do without a solid foundation. The shallow one will do its job quite well.
About typical projects of wood concrete houses
Conduct construction from this material only companies that have experience, as well as a staff of specialists of different profiles, can. To achieve success in this area, you need to have the best balance between price and quality. 
The more information about previous projects, the better. Let's take a few examples.
woodhouse group
Offers the construction of houses of any complexity, "for finishing". For example, standard house area of 101 square meter will cost about two million rubles, in the basic configuration. This price includes elements such as windows and roofing, ground floor ceilings, exterior finishes, walls inside and out, and foundations. Monolith not an exception.
The cost of construction also includes the costs of:
- For builders to live while they do the work.
- Storage of materials in warehouses.
- For transportation.
The rest of the estimate costs about 20-25 percent of the total cost. At a reasonable price, you can realize any modern ideas necessary additions. This usually refers to the internal fine finish for walls and ceilings, high-quality heating systems with the addition of regulation in automatic mode, heated floors and plastic windows.
"Arbolitstroykompleks"
Engaged in a wide range of construction services. In addition, the company creates its own wood concrete, which also successfully affects competition with other market participants. For all work performed official guarantee, at least 5 years.
Each project is developed individually for a particular customer, according to specific wishes. Basic equipment houses will cost about 14 thousand rubles per square meter.
AT basic kit Exterior finishing is not included. Monolithic walls You can also order if you wish.
"Arbostroy"
Engaged in the production of wood concrete, since 2006. There are only two groups of produced projects: "Comfort", "Standard". If you order a house with an area of 150 square meters, then all work will be performed at a cost of 16,500 rubles per meter.
Building instructions
Baths: the essentials
The most important thing is that we need baths for taking water procedures. Therefore, the level of humidity inside always remains high. In this case, even wood concrete walls will absorb moisture. But at the same time they let air through. But in this case wood concrete has many advantages compared to the same wood:
- No damage even after prolonged use.
- No cracks.
- The base does not swell.
- The form is not lost when interacting with moisture and steam.
Compared to a log house, wood-concrete baths are built much easier. Architectural ideas and sizes can be any. The arbolite blocks themselves can be laid in the same way as a brick.
How to build a garage?
In this case, there are no significant differences from buildings made of the same materials. Or from other block analogues. Wood concrete has the most similarities with a foam block. Unless the first one is much cheaper. And the garage itself can be anything, depending on the wishes and needs of the customer.
We present the video below. The shooting is quite old, but it clearly shows whether it is possible to build not only the garage itself, but also its basement from wood concrete. general review buildings and how it may look if this material is based on.
Recommendations for the construction of houses
In total, there are several stages in this process. We build a house using the following steps:
- Design.
- Foundation works.
- Creation of wall structures.
- Roof decorations.
- Organization of floor coverings.
- Warming.
- Communication connections.
- Finishes, inside and out.
We offer a video clip of one of the specialized forums. It was submitted by a user who describes his personal experience work with material. The cost of the house is about 800-900 thousand rubles. For the money this option is perfect.
About design
First you need to determine the composition of the soil along with its basic properties. Based on these data, the dimensions for the foundation are calculated. After that, other parameters are defined, like:
- Places where there are windows, doors.
- The introduction of insulation, or the rejection of it.
- Wall thicknesses.
- Configuration characteristics of the building.
Quantity, variety building materials also determined at the design stage. must be taken into account weather and features of a particular region. With a properly created project, there will be no overspending on materials. You will not need to think about additions and changes during construction.
We create the foundation
Compared to glass, wood or brick walls, arbolitovye put pressure on the ground much less due to their weight. Therefore, it is permissible to use the following types of foundations:
- Combined.
- Pile screw.
Thanks to such options, the cost, labor intensity of work is significantly reduced. The main thing is to pay attention to the issues of waterproofing and insulation. The temperature of the floor in winter is less dependent on the foundation with insulation. Roofing felt or roofing material will be the best solutions for waterproofing. Styrofoam helps to carry out warming. If the floor itself is insulated, then this is not necessary for the foundation.
Wall building rules
For blocks with a base of wood concrete, cement becomes a binder. Therefore, any mixtures based on the same material are suitable for laying blocks. Masonry mortars, adhesives, the traditional version - the use of any compositions is permissible. A hacksaw is used for cutting. Or saw, gasoline or electric. Fitting the parameters in place should not cause difficulties.
Strengthen every third or fourth row in order. The gasket runs over all blocks, under the adhesive or masonry mortar. Installation of windows and doors should also not cause difficulties, because the blocks have increased strength.
- Walls begin to be built from corners. In this case, plumb lines and levels are used, as well as ropes. The latter is pulled between blocks located on the edge. Then it will be easier to lay the remaining blocks, observing a strict line.
- The main thing is that the density of the masonry mortar is enough to complete the work. Excess material must be squeezed out by the weight of the block itself.
- The optimum temperature for building walls is +10 degrees and above.
- Arbolite blocks do not require soaking before laying.
When ordering material, it is necessary to separately ensure that it is not too wet. Otherwise, you will not be able to gain the required strength. If the raw blocks have already been delivered, then you need to let them rest for at least 15-20 days.
Next, we present a video. The Arbomaster company talks about the features of laying wood concrete blocks. The material can be used in the construction of any buildings up to three floors high. The story is quite detailed, as it is presented by masters of their craft.
The rest of the work
The creation of the roof, along with finishing and insulation, is carried out in the same way as in houses on other traditional foundations. It is necessary to use powerful self-tapping screws in order to connect the upper blocks to the Mauerlat. Finishing favor different materials- wood or plaster, and so on. The basis of wood concrete blocks is universal.
On specialized forums it is easy to find reviews on wood concrete houses. The ease and simplicity of working with the material is the main advantage for those who are engaged in construction on their own.
If we compare with, wood concrete is much more convenient to use. Laying is easy due to the light weight. If the owners live inside permanently, low heat losses are important. This helps to reduce the costs associated with heating in general. Blocks easily absorb excess moisture, so the inside is always dry. Once the builders wrote that even after more than twenty-five years of use, it was almost impossible to disassemble the wood concrete blocks without sophisticated equipment and devices.
Wood concrete, which is also called wood concrete due to the composition, was quite popular in domestic open spaces in the middle of the last century. The production technology came to us from Holland, and already in the 60s there were about a hundred factories producing wood concrete on the territory of the Union. It was used for the construction of buildings in the coldest regions of the country, as the material has excellent thermal insulation qualities. In the 90s, many factories went bankrupt, they forgot about wood concrete, but the buildings built decades ago are still in excellent condition. Today, the material is experiencing a new round of popularity, it is actively advertised, but few people know what wood concrete consists of, what are the pros and cons of it and what types it comes in. We hasten to rectify the situation and bring clarity.
No. 1. Arbolite composition
Arbolit is one of the varieties. In the name of the material, French roots can be traced: arbre is translated from French as “tree”. If you know this fact alone, you can guess what the main materials are part of the wood concrete. So this is:
It is clear that the characteristics depend on the quality of the raw material. finished material. Since the wood chips in the block of wood concrete are the most, then it is given the greatest importance. The composition should be exactly wood chips- not sawdust, hay, tyrsa or shavings (otherwise it will be sawdust concrete). The strength of the material depends on the caliber of the chips. According to the standards, the length of the chips can be up to 40 mm, width - 5-10 mm, thickness - 3-5 mm. It is desirable that the block contains only wood chips without any impurities, although a small amount of bark (up to 10%) practically does not affect the strength of the products. Wood type not so important, but usually used, and is used much less often, since it will be necessary to use large quantity additives due to the nature of the wood. 
Cement they use not lower than the M400 grade, but since it has the peculiarity of quickly losing strength properties during storage, it is better to use cement of the M500 grade in the production of structural wood concrete blocks.
Without chemical additives in the production of wood concrete, you can’t do it - it’s all the fault of the sugars contained in the wood, which prevent normal adhesion. Therefore, well-dried wood is used in production, but this does not save either. The surface of the chips is mineralized with lime, calcium chloride, or alumina sulphate.
The ratio of components is regulated by GOST. If, for example, the water content is exceeded, then a block of insufficient strength can be obtained at the output, and there will be more problems with its manufacture.
Arbolite is produced in several forms:
- masonry blocks;
- hollow blocks;
- thermal insulation boards;
- panels;
- solution for creating monolithic structures and pouring in place (similar to and).
Since arbolite blocks have found the greatest application, today they are meant by arbolite. As a rule, they are made in dimensions of 500 * 250 * 200 mm, but products with other parameters may be found. 
No. 2. Wood concrete production
The production of wood concrete blocks is a simple matter, but it requires precise adherence to technology. In short, then the process looks like this. Add all necessary to the water chemical substances. In the meantime, wood chips are poured into the mixer, water is added to it and mixed for a short time, then cement is added and mixed for another 3 minutes. Formation is carried out within 15 minutes in one of the following ways:
- hand molded without vibration;
- hand molding with vibration;
- manufacturing on a vibrating machine;
- production on a vibrating machine with a load.
Naturally, the mechanization of production makes it possible to obtain higher quality blocks with the necessary performance. Pressing the mixture ensures the correct distribution of chips in the cement and its complete coverage with cement mortar. Vibration is applied carefully to achieve an even distribution of the chips, but not cause the cement slurry to settle on the bottom of the mold. 
No. 3. Arbolite: pros and cons
The composition of wood concrete blocks allows us to talk about numerous advantages of the material:
- excellent thermal insulation. The thermal conductivity coefficient of wood concrete with a density of 400 kg / m 3 - 0.07 W / m * K, with a density of 500 kg / m 3 - 0.09 W / m * K, 600 kg / m 3 - 0.11 W / m * K, 800 kg / m 3 - 0.15 W / m * K, and blocks with a density of more than 500 kg / m 3 are already considered structural. According to calculations, for temperate latitudes, a 38 cm thick wood concrete wall is enough to provide the required resistance to heat transfer. In practice, walls are usually built 30 cm thick, and the inner and exterior finish slightly increase thermal insulation. Together with arbolite blocks it is good to use, and then the problem of providing thermal insulation is quickly solved;
- good sound insulation;
- excellent vapor permeability, therefore, an optimal microclimate is maintained in the house of wood concrete;
- high fire resistance. The material belongs to slow-burning (combustibility group - G1), difficult-to-ignite (B1) and low-smoke-forming (D1) materials;
- light weight allows you to save on and simplify the process of building a building;
- ease of processing;
- environmental friendliness;
- resistance to and rodents;
- high strength. Cracks do not form on the surface of the blocks. Buildings can be erected without additional inter-row reinforcement;
- ease of installation of fasteners, incl. and self-tapping screws, which distinguishes the wood concrete block from polystyrene concrete or expanded clay concrete.
Cons of wood concrete:
- the need for protection from direct exposure to moisture. Cement and mineralized wood chips have low hygroscopicity, but in direct contact with water (for example, rain with wind), the block can get wet and lose some of its positive properties, therefore, it is better to additionally veneer buildings from wood concrete, but there is nothing like that - houses from many other materials are also finished for reasons of aesthetics or protection. It should be noted that there are cases of operation of buildings from wood concrete without additional exterior finish Nothing has happened in 10 years
- not the highest frost resistance. The block withstands 25-50 freeze / thaw cycles, depending on the strength, but by protecting the material from direct exposure to moisture, the life of the material can be significantly extended;
- insufficient geometry accuracy, even if all production requirements are met. For example, they have much more accurate geometry. The deviation in the parameters of the blocks leads to the need to increase masonry mortar, and this leads to freezing of the walls at the seams. AT recent times some manufacturers began to resort to milling blocks to improve their geometry;
- the price of wood concrete blocks is about 1.5 times higher than aerated concrete and foam concrete;
- abundance on the market of arbolite garage production with unknown performance;
- in order to maintain the vapor permeability of the house, it is necessary to use only breathable materials for finishing the facade, but this is not a minus - rather, a recommendation.
Wood concrete today is widely used in private construction for the construction of houses (up to 3 floors), cottages, garages and outbuildings, the material is also in demand in the construction of low-rise industrial buildings. Shrinkage is 0.4-0.5%. 
No. 4. Wood concrete density
The density of wood concrete blocks is the main indicator that is taken into account during the selection and purchase. The higher the density, the more durable and resistant the material. On the other hand, a lower density provides better thermal insulation qualities, so the blocks should be selected depending on the purpose of use.
By density, arbolite blocks are divided into:
There is also a classification of blocks with the allocation of structural and heat-insulating material with a density of 450-600 kg / m 3.
If it's about erecting the walls of the house monolithic technology , then a solution with a density of 300 kg / m 3 has the same good bearing capacity, which is a block with a density of 550 kg / m 3. Besides, monolithic walls, "grown" in a monolithic way using formwork, do not have cold bridges.
No. 5. Strength of wood concrete blocks
The bearing capacity of wood concrete blocks directly depends on the compressive strength of the material. As the density increases, the strength increases. Strength is determined by brand and class. Brand - the average value for a whole batch of samples, ranges from M5 to M100, where the number shows how many kg cm 2 of the block surface can withstand. In a batch of the M75 brand, blocks can withstand 65-80 kg / cm 2, and for large blocks this is a very significant discrepancy, so strength classes are often used today. The class determines the guaranteed strength, i.e. 95% of all samples must meet the specified parameter. Wood concrete classes range from B0.35 to B3.5.
The scope of use of wood concrete directly depends on its strength:
- heat-insulating the material has a strength class up to B1 and a strength grade up to M10;
- structural strength class up to B3.5 and strength grade up to M100.
Blocks B1 can be used in the construction of low (up to 3 m) one-story buildings, for taller buildings it is better to take blocks B1.5, and for 2- and 3-story houses - blocks B2.0-B2.5. 
No. 6. What to consider when choosing wood concrete?
Manufacturers of wood concrete blocks today there are a lot, we will not single out anyone specifically, since there are worthy companies in each region and it will take a very long time to list them. On the other hand, everywhere is full and handicraft industries, who are trying to sell frankly bad goods at a higher price, and even a quality certificate is not always a guarantee of actual quality, because we all know how documents are sometimes made. It is best to visit the production, evaluate the technology and quality of the blocks with your own eyes. By what criteria to check and how to understand that the product is of poor quality?
No. 7. Do-it-yourself arbolite blocks
Numerous reviews of private builders indicate that Wood concrete is better to buy ready-made than to produce it yourself. The technology seems to be not complicated, but it is difficult to achieve the necessary strength at home, and the laboriousness of the work is very high. Moreover, it is better not to use self-made wood concrete for masonry. bearing walls, but or a garage can be built from it, so we give instructions on how to make arbolite blocks with your own hands:
To improve the quality of the material, it is better to get a vibrating table and detachable forms. The composition and proportions of the mixture may vary depending on the desired result. 
For use, arbolite blocks with a size of 500 * 250 * 300 mm or 500 * 250 * 200 mm, masonry is carried out in one or one and a half blocks, partitions are erected from blocks of 500 * 250 * 150 mm. It is advisable to take a drying break after every 3-4 rows of masonry. When erecting low-rise small buildings, reinforcement is not required - in other cases, it is better to lay reinforcement every 3 rows. A house made of wood concrete will last at least 60 years (this is how long the first houses made of this material turned out to be, and they are still in excellent condition) - it is only important to choose quality material with the required performance.
Building a storage space vehicle- a fundamental task for a true motorist. In this case, the design must perform certain functions.
Well, after all, it’s not a barn, a chicken coop or a simple utility room that is worth it, but real home for a particular family member. Wood concrete blocks allow you to get an excellent and inexpensive structure, so a garage made of wood concrete can be found more and more often.
We build a garage from block wood concrete
The construction of a building from wood concrete does not have significant differences from the construction of others block materials. The greatest similarity will be with the foam block, except for the fact that wood concrete will be cheaper. To build the same chicken coop or barn it is also better to use more cheap material, especially since it is quite often used for building houses (if a person feels good in such a structure, then the material is suitable for other purposes). Like all construction processes, the construction of a garage from wood concrete blocks must be carried out according to a certain algorithm.
Create a project
Without preliminary design, it is unlikely to be able to build a structure that can satisfy existing needs. To begin with, it is worth understanding what functions the garage should perform: exclusively storing the car or also carrying out its repair. In the second case, construction begins with the construction of a revision pit.
Before arranging the pit, do not forget to check the level ground water, otherwise you will have to do repairs in scuba gear. In any case, waterproof the walls. It is not recommended to use wood concrete for their arrangement - it is susceptible to moisture, so it is better to lay the walls out of brick or cinder block.
Also for the construction of the garage you need detailed project. Some try to do without it, but professionals draw a drawing even if a barn or a chicken coop is being built, although they can build it “by eye” without any problems. An accurate project is a guarantee of the durability of the structure and its compliance with the goals set.
To create a project yourself - use special programs or find a ready-made one. It also does not hurt to show the project of a garage made of wood concrete blocks to geologists and engineers. Only in this case can you be sure that a particular structure will have desired characteristics in the conditions of the chosen area.
Plot marking
Marking the site for the foundation
Take the project, pegs, fishing line (you can rope) and mark the perimeter of the future garage. pay attention to standing side by side structures. If they are already erected, then it is better to retreat from them a little.
When excavating the earth to create a trench under the base, there is a possibility of violating the strength of the foundations of other buildings. Tampering can destroy a barn, a chicken coop, or even an entire house.
Foundation construction
A feature of the construction of light wood concrete blocks is that there is no need to include a deep base in the project. A structure made of 90% organic material (wood) will have a low mass. Therefore, the usual strip foundation will be quite enough.
To arrange a site for a car, you can use any preferred option: pour concrete, use special blocks, lay out paving slabs(paving stone, wave, reel, rhombus, etc.).
A trench for a garage made of wood concrete blocks, in most cases, is made a meter deep. The width depends solely on the thickness of the walls (50-70 cm).
A layer of sand is poured at the bottom of the trench - a special pillow. It is also recommended to waterproof the walls before pouring the mortar.
Solution preparation
Now relevant in the construction of structures from blocks to use special adhesives, but in this case its use is irrelevant. From a material point of view, this is the same as building a chicken coop from gas blocks. Moreover, for wood concrete with its non-ideal surface, it is optimal to use it cement mortar capable of compensating for all irregularities. As for proportions, there is no need to invent anything new. Preparing a standard cement mixture.
Wall masonry
The process is similar to building from other blocks and bricks, so it will not be described in detail. Just note that you need to start from the corners and constantly check the evenness of the rows with the help of a level.
Installation of the opening beam
This stage is considered to be the most difficult in the construction of the garage. Note that the project should initially contain data on the width of the opening (for 1 car - 3 meters or more). Also, heavy monolithic structures from reinforced concrete, therefore, in order to prevent an emergency load on the wood concrete, it is necessary to build strapping belts to strengthen the beam supports.
Roof installation
Its design may be the simplest. For example, you can look at a chicken coop or other building in which there is no attic space.
Roof construction algorithm:
Internal work
When constructing a conventional building, it is enough to carry out insulation to protect the car from atmospheric phenomena. conventional materials: mineral wool or polystyrene.
Before internal works consider the location of the shelves and potbelly stoves, if such are planned to be installed.
It is also necessary to carry out waterproofing to protect the walls from moisture. To do this, use polyethylene and drywall, and then paint the surface with paint of the desired color.
outdoor work
Plaster with reinforcing mesh
Outside, it is also worth protecting the walls from the effects of frost and moisture. The easiest option: a layer of foam, on top of a reinforced mesh and plastering. The plaster is also painted. After that, you can put the gate and "acquaint" the car with its new home.
Building a garage from block wood concrete - perfect solution capable of providing optimal conditions to store a car within a small budget. Only when buying, choose trusted manufacturers, unless, of course, you want to find garbage in the middle of the blocks when sawing and watch how the walls literally crumble before your eyes.
