The use of wood concrete in various construction works. Arbolit: we use for construction The main properties of blocks

Wood concrete, which is also called wood concrete due to the peculiarities of 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 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 more quality blocks with the necessary operational qualities. 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 uniform distribution chips, but not lead to sedimentation of the cement slurry 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. 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 impact 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 a number of its positive properties, so it is better to additionally veneer buildings from wood concrete, but there is nothing like that - houses from many other materials for reasons of aesthetics or protection are also finished. 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. Deviation in the parameters of the blocks leads to the need to increase the masonry mortar, and this leads to freezing of the walls at the seams. V Lately 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.

Density wood concrete blocks 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 we are talking O 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 laying load-bearing walls, but you can build a garage from it, so we give instructions on how to make wood concrete 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 stand for at least 60 years (this is exactly the age of the first houses made of this material, and they are still in excellent condition) - it is only important to choose quality material with the required performance.

The construction of a place to store a vehicle is 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 other 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 for other purposes material fit). Like everyone else 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 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, you can be sure that a particular building will have the necessary characteristics in the conditions of the selected 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 it is important to use special adhesives when building structures from blocks, 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.

Monolithic wood concrete is one of the most economical building materials used for more than 50 years in different countries for low rise buildings. Economical construction from sawdust concrete, as it is called, according to its composition, will be in demand at all times, especially when erecting secondary walls of industrial workshops or for private suburban housing construction. In monolithic walls, the arbolite mass is poured into the prepared formwork, and for the traditional construction of a house, a mixture of concrete and sawdust is formed in the form of blocks.

Properties and composition of wood concrete

The advantage of the material is the minimum cost, low thermal conductivity, ease of manufacturing technology and the composition of wood concrete. brick blocks from a mixture of sawdust and concrete with some impurities are affordable and reliable, they are easy to make with your own hands right on suburban area which will result in additional savings. Its minimal thermal conductivity makes it desirable even in cold climates. Forms for filling with the prepared mixture are easy to make on your own, taking into account the required dimensions, and if necessary, the material lends itself well to sawing.

Like foam concrete, sawdust concrete is classified as a building material from the group of lightweight concrete. He is somewhat similar artificial stone, made on the basis of woodworking waste - these are chips, small chips and sawdust. Wood concrete photo - varieties of material use in construction.

Today, wood concrete is formed in the form of slabs, blocks, panels and monolithic walls. The standard release of wood concrete material is outdoor blocks 20x30x50 cm and small panels, and partitions and piers are made from blocks 20x20x50 cm. arbolita of other sizes. The diameter and shape of the internal voids, as well as the composition of the material, also vary. According to GOST, arbolite blocks have an internal coating with a concrete-lime mortar that prevents moisture.

Depending on the climate zone and natural conditions, other dry plant components are often added to sawdust. Similar technologies for making bricks have been known since antiquity, but the most widely used mixture of straw and clay, and today experimenters in creating economical building materials focus on a mixture of concrete with industrial waste.

In the post-war period, during the period of active Soviet construction, sawdust blocks were widely used due to their availability and economy. Besides monolithic wood concrete, wood mixture with concrete was poured in the form of a hollow brick. At the same time, arbolite can have both standard and arbitrary sizes, it is important that they are convenient for laying.

Analogues similar to domestic building materials are popular abroad:

• woodstone,
• duripanel,
• Durizol, etc.

Today, wood concrete is used for the construction of:

• piers in the construction of industrial buildings;
• garages;
• outbuildings;
• country houses;
• storage facilities;
• holiday villages;
• typical cottage construction.

In low-rise houses, arbolite is used for the construction of not only internal walls, but also external, requiring facing finishing, for example, siding or "wild stone". Cast from wood concrete bearing walls and secondary piers, also from small hollow blocks make lightweight structures for fences or partitions. In addition, in the cold climate zone, it is successfully used for an additional second layer when insulating external stone walls, that is, as thermal insulation - wood concrete video.

The density of heat-insulating and structural blocks is within 400-850 kg/cu.m.

The thermal conductivity of wood concrete is 0.08 W / m-0.17 W / m, that is, higher than that of foam concrete, expanded clay concrete and all types of bricks.

Frost resistance of building material - F25-F50, was used as an experiment in arctic and antarctic construction.

Fire resistance indicators - 0.75 h-1.5 h, does not ignite.

According to indicators of resistance to damage by rodents, termites, bacteria, fungi and rot - classification of biostability of group V.

What is included in the arbolite

Arbolit are blocks consisting of a two-component mixture - a filler from wood waste and lightweight concrete with a small amount of chemical stabilizers for the durability of wood. Despite the woody base, country houses do not differ in strength, sound and heat insulation from more expensive materials. The only requirement is finishing.

The material is fire resistant, does not shrink, conditionally has 2 varieties - structural (more dense, full-bodied) for external walls and heat-insulating with voids for interior work and upper floors. Light blocks are successfully used to lighten the upper floors in small buildings on soils where it is not recommended to build large and tall private houses.

The basis of the composition of wood concrete:

• sulfate-resistant or Portland cement;
• wood-organic filler;
• chemical additives.

Chemical stabilizers can give wood concrete additional properties:

• remove excess polysaccharides from cellulose for material durability;
• significantly increase bactericidal performance;
• adjust the porosity of sawdust, etc.

Under the filler use dry wood waste:

• wood chips,
• shavings,
• sawdust,
• crushed bark and needles,
• hard stems of agricultural crops (cotton, cereals, rice straw, etc.), depending on local raw materials.

Thanks to this technology, in order to save money, building materials from improvised plant waste can be made in remote agricultural regions. Do-it-yourself arbolite production can be mass-produced - for local needs.

There are other options, respectively, technologists for the production of wood concrete blocks, for example, sometimes use liquid glass with ash, lime, sand, slag and other components.

Basic properties of blocks

The properties and technology of wood concrete combine the advantages of concrete and natural eco-materials for construction. For example, concrete gives it strength, and wood gives it a tendency to self-ventilate, retain heat and absorb odors. Like all building materials, wood concrete has its drawbacks and obvious advantages.

1. The main advantages of building materials:

• versatility in construction - the ability to cast monolithic walls, blocks, slabs, lintels for window and doorways required shape and size;
• wood concrete can be processed (sawing and drilling), makes it possible to obtain blocks of the desired configuration, for example, triangular, for leveling a row of peaked roofs;
• economical building material from improvised ingredients;
• the simplest production technology and the ability to manufacture blocks directly at the construction site;
• hardened wood concrete has high adhesion, lends itself well to cladding and finishing, often without a frame and reinforcing mesh;
• due to high thermal insulation, wood concrete houses are distinguished by lower heating costs than stone counterparts;
• wood concrete is fire resistant, despite the wood content;
• not subject to rotting and fungal attack;
• frost-resistant material;
• high sound insulation, it is favorable for use in the construction of houses near railway tracks and airfields;
• the lightness of the material makes it indispensable on problematic soils;
• environmentally friendly wood concrete is appreciated by allergy sufferers and supporters of eco-building technologies;
• homogeneous material with equal distribution mixtures;
• gives the least waste when sawing, and broken blocks are easy to glue with mounting glue;
• saves time when laying, thanks to large and light blocks;
• has a low specific gravity;
• does not shrink;
• perfectly holds fasteners (screws, nails, dowels) and light fittings for decorative finishing.

2. Arbolite also has its disadvantages:

• requires the construction of a high concrete foundation for the construction of a country house with waterproofing, if a country plot is being built in places high humidity. This is due to the porosity of the material, and it is very difficult to bring the water that has stuck to the outside, because the wood concrete is characterized by high water absorption - up to 50-80%. Due to the low moisture resistance, a protective finish of the outer layer is required;
• ready-made blocks can not always be bought, and making wood concrete with your own hands is sometimes problematic. In many places, this simple and well-forgotten technology is only being revived. Do-it-yourself arbolite video gives a complete picture of the production technology, which should be carefully studied before you start making it yourself.

Wood concrete production

The arbolite mixture for forming blocks is prepared in different ways, depending on the technology. For example, based on a concrete mixer, liquid glass, wood shavings, and Portland cement grade 500.

For the production of large volumes of wood concrete, special equipment can be rented or purchased. To do this, you will need equipment for:

• kneading,
• rammers,
• laying in molds,
• drying ovens,
• curing area, protected from moisture.

Detailed technologies for the industrial production of wood concrete blocks are available from specialized companies that sell them together with a set of equipment. In domestic use, you can use the simplest recipes, the method of grinding woodworking waste and the technology of wood concrete, however, even here you can not do without a concrete mixer and forms for obtaining blocks.

Forming blocks from wood concrete

The best filler for the mass under the wood concrete will be sawdust of different fractions mixed with crushed chips, treated with lime mortar, which have already been exposed (drying) for 3-4 months in air. sawdust soaked in lime mortar, kneaded and dried, it will remove the polysaccharides from the pulp to eliminate the causes of decay and swelling.

The shape for rectangular blocks can have arbitrary sizes, but it is better to use the standard - 25x25x50 cm. The boards inside should be as smooth as possible. Pieces of film linoleum can be additionally treated with KN-3 mastic.

Experienced craftsmen recommend making molds for wood concrete blocks from scraps of boards with their own hands, and for the convenience of excavation finished products It is advised to stuff pieces of linoleum on the walls. The mixture during the filling of the form can be compacted by hand with any device suitable for this. If there is a ready-made vibropress, you can use it.

The filled block is kept for a day inside the mold, after which it is laid out under a canopy for hardening. Some technologies recommend keeping the blocks under the film for final hydration for 1.5-2 weeks. Low temperature storage space does not affect the quality of wood concrete blocks, but you should not leave them in the cold. In the heat, the blocks can dry out and crack, so they are periodically sprayed with water.

It is convenient to knead the sawdust-concrete mass in a metal trough or box, where the sifted sawdust and crushed chips are laid out, poured with a solution of water with chemical additives. The wetted substrate is well mixed until homogeneous, then sprinkled with cement, mixed and dry cement is added again until a thick consistency is obtained. The most convenient mixing is obtained in a small concrete mixer.

Correct proportion:

• 1 part volume - sawdust plus chopped wood chips,
• 1 part volume - dry cement,
• 1.5 parts of water with additives up to 4-5%.

There may be more cement, while the wood concrete will be stronger, but heavier, and for a porous and hollow material that goes for insulation and a wall, less cement is added.

For additives used:

• liquid glass;
• calcium chloride;
• aluminum sulfate or aluminum;
• slaked lime.

When filling the mold with a mixture to obtain wood concrete, you can insert 2-3 identical wooden throws to obtain voids. The mass is laid in layers in 3 stages, followed by compaction with any suitable device such as a bit or wooden hammer. For wood concrete under the first floor, reinforcement can be added between the layers. The excess must be removed, the top is leveled, for example, with a wide construction spatula, the form is exposed under a canopy for concrete to harden.

When removing the finished arbolite block, we turn the form over onto a flat area and the hardened material stands for a week under the film and finally dries 3-8 days before laying.

It is better to make the first batch small - to check the properties of the resulting wood concrete. Can be tested for sawing, punching and holding nails.

Arbolite is an excellent choice building material, for building a garage.

What are the requirements for the construction of a garage?

The garage should provide reliable storage of the car !!!

First of all, a garage is built to protect the car, and.

Protection from external atmospheric (and not only) influences.

Everything here is clear enough without unnecessary explanations. You protect your steel horse from rain, hail, freezing of ice crusts, falling branches, trees, icicles and other "pleasures", broken glass and scratches on the body "from well-wishers" and children. The occurrence of these events is quite likely when your car is just standing on the street.

Let's take a closer look at protection against malicious intent.

The uniqueness of arbolite blocks, which fundamentally distinguishes them from blocks made of lightweight concrete with other fillers, lies in their plasticity (property of wood) and a large adhesion surface with masonry mortar(property of chips). As a result, we get a monolithic elastic wall, from which it is IMPOSSIBLE to knock out a single block. To destroy the arbolite wall, you need an electrified tool (grinder, puncher, etc.). It’s almost IMPOSSIBLE to just get by with one valda. To destroy the wall of wood concrete using hand tool much more time is required and much more noise will be produced. This is an undesirable factor for a person trying to enter your garage. The wall will spring, crumble at the points of impact, but hold on. It is much easier to cut off a gate or gate with a grinder and enter the garage than to destroy a wall of wood concrete.

Humidity protection.

The car is basically iron. Iron, when interacting with oxygen contained in atmospheric air in the process of a chemical oxidation reaction, passes into the state of iron oxide Fe2O3 - rust. Especially actively, this reaction proceeds in conditions of high humidity. Therefore, even when your car is standing, and not driving through puddles, it rusts. Especially active if before that you drove through puddles or snow.

Our motorists have long noticed that if you put a car in an iron or stone garage, the rusting process is quite active. If you lay on the floor wooden planks, this process slows down significantly. This is due to the fact that wood, like a sponge, absorbs excess moisture, reducing its concentration in the surrounding atmosphere, which leads to a slowdown in the rusting process of the car.

Now imagine that your car is surrounded by wood not only from the side of the floor, but also from the side of the walls, which, absorbing excess moisture from the air, remove it through capillaries to the atmosphere outside the garage. What will be the effect of this? That's right, the amount of moisture in the atmosphere will decrease even more, the time it takes to remove moisture from the garage will decrease and your car will serve you even longer.

The garage must be fireproof !!!

The fire-fighting properties of wood concrete have been repeatedly proven, both in laboratory tests and in the field. Wood concrete cannot be ignited and does not support combustion!!!

The normative time, when conducting fire tests, products from wood concrete, is 1.5 hours. A similar indicator has products from foam blocks.

The presence of a cement cocoon, which excludes the access of oxygen to wood, and its very low thermal conductivity, lead to the gradual destruction of the block ONLY in the place of fire exposure. Videos demonstrating this property of arbolite are posted on the Internet in sufficient numbers.

The garage should provide comfortable conditions for the operation of the car !!!

Wood concrete is such a warm material that in completely severe frosts, a car put into a garage of wood concrete blocks in the evening starts up quite calmly in the morning without additional heating and other movements.

The heat stored in the engine and car body is enough to heat the air in the garage to a temperature sufficient to start the car in the morning and maintain this temperature for several hours.

In addition, in our conditions, a garage is a place where very often its owner is engaged in its maintenance, depending on its auto qualification. And not just service.

We emphasize once again that wood concrete is very warm material. This means that a comfortable temperature in the garage can be achieved with the help of simple and inexpensive energy sources in a very short period of time (provided that you have well-insulated gates, a gate and a roof of the garage. After that, you can completely surrender to your favorite business.

In addition, the arbolite is perfectly ditched, nails are driven into it, screws and self-tapping screws are screwed in. The walls are so strong that shelves of almost any weight can be fixed on them. And this means that you can completely equip the garage with your own hands to suit your needs: hang shelves to accommodate spare parts and tools, place large-sized parts on the walls (so that they do not get in the way under your feet), lay electrical wiring in boxes or walls. At the same time, you are completely deprived of such "pleasure" as the selection of dowels, anchors and their fastening in the wall. Just take a self-tapping screw or a hook with a screw corresponding to the required load, choose a mounting location. In the case of a self-tapping screw, simply screw it into the wall. In the case of a hook, we drill a hole in the wall with a simple drill along the smaller diameter of the hook thread, and simply screw it into the resulting hole.

Using this technique, shelves, cabinets, spare rubber, large-sized parts, tool fixtures can be placed on the walls. Those. EVERYTHING (!!!) that can be placed on the walls, freeing up the floor and the lower space of the garage for comfortable work.

At the same time, labor costs will be an order of magnitude lower than the same work with walls made of other building materials.

Building a garage should not undermine the family budget !!!

We tried to cover in sufficient detail the factors affecting the cost of construction from wood concrete blocks on the page dedicated to the construction of a bath. Everything described on it is also relevant for the construction of a garage.

Build a garage - only from wood concrete !!!

Based on the foregoing, we believe that the most good material according to the criterion price / quality / comfort are wood concrete blocks.

For understandable money, you get the opportunity to build a very durable and warm structure in the shortest possible time, which allows you to efficiently maintain and maintain your car.

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 the construction of low-rise buildings and structures. Dachas and country houses, outbuildings are built from it. 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 both specialists and consumers testify to 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. To prepare the mixture, cotton, rice straw, flax and other industrial crops are used. ready mix pour into a mixer and mix 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 a more durable material from which you can build buildings with a higher height. 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 from brick, precast or monolithic reinforced concrete. The first row of blocks is laid on the top of the plinth or foundation. First lay out the corners and intersections of the outer and inner 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.
