How to make wood concrete blocks with your own hands?

When choosing a material for building a house, many developers prefer blocks, the use of which allows to reduce the construction cycle. The building material used is subject to requirements for environmental friendliness, strength, thermal conductivity and soundproofing properties. Gradually, interest in wood concrete, made from wood chips mixed with cement, is increasing. By making wood concrete blocks with your own hands, you can significantly reduce the overall level of costs. Let us consider in detail the features of the technology.

Chip blocks - advantages and disadvantages

The performance characteristics of wood concrete are determined by the following points:

• properly selected components;
• the ratio of ingredients in the mixture;
• compliance with technological requirements.

Self-made blocks from wood chips have several advantages:

• low level of thermal conductivity. The heat-conducting properties of wood concrete are comparable to wood. In a wood concrete building with a standard wall width, a comfortable temperature is maintained with minimal heat loss;
• sufficient strength. The material withstands compressive loads up to 5 MPa, as well as bending forces up to 1 MPa. Arbolite retains its integrity with uneven shrinkage of the structure, it is able to restore its shape;
• freeze resistance. Performance is maintained for 30-50 deep freeze cycles. The frost resistance of the material is quite high;

Let's immediately determine that wood concrete and sawdust concrete are different materials with different characteristics.

• increased soundproofing properties. Wood chips, which is a filler, effectively absorb external noise. This allows you to reliably soundproof the room, providing comfortable conditions for residents;
• small weight. Using lightweight wood concrete products with increased dimensions, it is possible to erect the walls of a building in a limited time. In addition, due to the light weight of the walls, the load on the foundation is significantly reduced;
• ecological purity. The use of environmentally friendly components for the manufacture of wood concrete eliminates the release of harmful substances during operation. The material is absolutely harmless to others;
• usability. The material is easily processed using household tools. There are no problems when drilling, cutting, and the need to use reinforcing meshes when plastering walls is eliminated;
• slight shrinkage. The value of the indicator does not exceed 0.6%, which confirms the preservation of the geometric dimensions of the walls under the action of the load. Block building material retains its dimensions after drying;
• low cost. The use of inexpensive woodworking waste, which accumulates at specialized enterprises, makes it possible at low cost to produce the number of blocks necessary to build a house.

Along with the advantages, . Weaknesses:

• increased hygroscopicity. The moisture absorption of wood concrete reaches 85%. Care should be taken to ensure reliable waterproofing of the foundation of the building, as well as thorough plastering of the walls from the inside and outside of the building;

The characteristics of the arboblock are not bad. Pluses still need to add light weight, large size and good ability to absorb sounds

• structural changes of the arbolite array during heating. Despite the fact that wood concrete does not ignite under the influence of open fire, at elevated temperatures the material loses its strength due to smoldering wood chips;
• increased dimensional tolerances. Deviations from standard sizes are caused by making molds for wood concrete blocks with your own hands. As a result, the need for plaster increases.

The disadvantages include an increased interest in building materials from rodents, as well as the possibility of the development of microorganisms with a reduced concentration of lime.

Do-it-yourself arbolite blocks manufacturing technology

The production process of products from wood concrete is similar to the technology for manufacturing products from lightweight concrete. Observing the technology and choosing the right recipe, you can make ordinary blocks, as well as non-standard arbolite slabs with your own hands. Developers are attracted by the simple recipe and the availability of components. However, there are a number of nuances.

Ingredients used

Do-it-yourself arbolite blocks are prepared from the following ingredients:

• Portland cement marked M400. The binder must be loose and fresh to combine the components of the mixture into a common array with the necessary strength;
• special additives. Calcium chloride, silicates, aluminum sulphate, lime or calcium nitrate are used as mineralizers. They reduce moisture absorption, and also prevent the development of microorganisms;

Arbolite belongs to lightweight concrete, the technology is almost standard, with the exception of some nuances: the need for pressing and using not an ordinary gravity concrete mixer, but a forced

• wood chips. It is used as a filler, must be cleaned of foreign matter, dried and have a certain size. The aggregate is also treated with lime to prevent decay;
• water. The use of purified water is recommended. Moisture is gradually absorbed by the filler, and it is saturated with mineralizers included in the mixture.

The quality of building materials is affected by the correct preparation of raw materials. Woodworking waste should be soaked for 4-7 days, stirring regularly. This allows you to reduce the sugar content in the raw material.

Component ratios and product dimensions

By changing the concentration of components in the working mixture, it is possible to manufacture products for various purposes, differing in density:

• heat-insulating, with a specific gravity of 0.5 t/m3;
• structural, the density of which is 0.5–0.85 t/m3.

With an increase in the specific gravity, the strength characteristics increase, according to which the classification of products is carried out.

The cement must be dry and fresh. Chips - a certain size

Thermal insulation blocks corresponding to class B0.75 are used for thermal insulation of main walls and include the following ingredients per 1 m3 of solution:

• chips - 0.18–0.2 tons;
• portland cement m 0.25–0.3 t;
• water - 0.3–0.35 t;
• calcium chloride - 8-10 kg.

Relate to light wall building materials. They are made from sawdust, wood, cement, water and other components.

Wood chips, which are chopped wood, are used as the main component. Such blocks have a greater strength limit than foam blocks and gas blocks. Important characteristics of the material are: high crack resistance and impact resistance.

The initial stage in the production of wood concrete is the thorough preparation of all the necessary components, followed by the preparation of the base, its casting into molds for further blocks.

Foundation preparation

The filler for blocks includes shavings and sawdust in a ratio of 1:2 or 1:1. they must be well dried, for this they are kept for 3-4 months in the open air, periodically turning over and treating with a solution of lime.

In the latter case, for 1 cu. meter of raw materials need about 200 liters of lime solution 15%. It will contain wood components for 4 days, which need to be mixed 2-4 times a day.

At this stage, the main goal is to remove the sugar contained in the sawdust. It can cause them to rot further.

Chips can be bought ready-made, or you can make it yourself by building a wood chipper. What it is and how it works, the video will tell:

Required Components

After the sawdust is prepared, the following additives are added to them:

• Slaked lime;
• Sulphate of calcium and aluminum;
• Portland cement 400 brand;
• Soluble liquid glass;
• Calcium chloride.

As a rule, the proportion of these components in the arbolite mixture does not exceed 4% by weight of cement. They give the final product resistance to decay, provide high refractoriness and plasticity.

Manufacturing technology

Arbolite blocks have an optimal size of 25 cm * 25 cm * 50 cm. They are convenient not only in the manufacturing process, but also when laying. The casting process is as follows: the blocks are filled with an arbolite mixture of three layers. Each approach is followed by careful compaction with a wooden mallet sheathed in tin.

The excess mass is struck with a ruler, and the form is kept for a day with an air temperature of + 18 ° C. After the time has elapsed, the blocks are removed from the molds by a slight tapping and laid out on a flat base for complete hardening for 2 days and drying for a period of 10 days.

In the photo - the process of removing the wood concrete block from the machine after molding:

Equipment

To produce wood concrete blocks, different equipment may be required depending on the volume of production and the raw materials used. The manufacturing process of this building material and its final result must meet a number of criteria: GOST 19222-84 and SN 549-82.

Most often, the remains of coniferous trees are used for the production of wood concrete. Their grinding is carried out on a chipper (РРМ-5, DU-2 and others). A more thorough crushing process is carried out on crushers (DM-1) or hammer mills. On vibrating tables, pieces of earth and bark are separated from the crushed wood mixture.

The arbolite mixture itself is recommended to be prepared on paddle mortar mixers or mixers of forced cyclic action. It is possible to transport the finished mixture to special forms using kyubels or concrete distributors. And the lifting of the conveyor itself should not exceed 15o up and 10o down at a speed of up to 1 m / s. The fall of the mixture should be carried out at a height of not more than one meter.

Compaction of structures can be done both with manual rammers and with a vibropress (Rifey and others). If it is necessary to make blocks from wood concrete in small volumes, then you can use a special mini-machine. If we are talking about industrial scale, then they use entire lines for the production of wood concrete blocks, which include machines for making blocks, presses and mixers.

It looks like a line for the production of arbolite blocks

The best curing process is achieved by using heat chambers with heating elements, infrared radiation, etc. They can control the required temperature and humidity level.

Block molds

Forms for the production of wood concrete blocks can be of the following sizes: 20 cm * 20 cm * 50 cm or 30 cm * 20 cm * 50 cm. For the construction of structures from wood concrete blocks, forms can be produced in other sizes (for floors, ventilation systems, etc.) .).

Forms for blocks can be bought, and you can also make your own. To do this, you will need boards 2 cm thick, which are knocked into the shape required in size. The inside is sheathed with plywood and top with a film or linoleum.

Scheme for making molds for wood concrete blocks

How to make wood concrete blocks with your own hands

Equipment list:

• Detachable form and inserts for it;
• Falling and vibrating table;
• Mold lifter;
• Shock-shaking table;
• Mix tray;
• Metal mold tray.

Having all the necessary equipment for the production of blocks, you can get 300-400 m3 of building material per month. At the same time, the area for the installation of all equipment will require about 500 square meters. m and electricity costs 10-40 kW / h.

The manufacture of large blocks requires additional reinforcement. When the form is half filled with wood concrete mixture, a layer of concrete with reinforcement is poured on top, after which filling with wood concrete continues.

When self-manufacturing blocks from wood concrete, organic substances must be filled with water, after which - with cement until a homogeneous state. This will require 3 parts of cement, 3 parts of sawdust or wood shavings and 4 parts of water. The resulting mixture should be free-flowing and at the same time hold its shape when squeezed in the hand.

Before pouring, the inside of the mold is smeared with lime milk. After that, you can lay out the prepared mixture in layers with careful tamping. The surface of the block is leveled with a spatula and filled with plaster mortar to a height of 2 cm.

Video on how the production of arbolite blocks with their own hands is carried out:

• The mixture can be compacted with iron-studded wood.
• The blocks that were under the film in a wet state for about 10 days have the greatest strength. In this case, the air temperature should not be lower than 15 degrees.
• You can prevent the blocks from drying out by periodically watering them.

It is enough just to make this building material yourself. If you follow all the technologies, then the final product will be easy to use, have high strength, fire safety and a long service life.

For the construction of houses, various types of block materials are used to speed up construction. When choosing blocks, it is important to take into account the strength of the material, environmental friendliness, heat-insulating and sound-conducting properties. The interest of developers to wood concrete, which is produced on the basis of cement and wood chips, has increased. It is not difficult to make block arbolite and arbolite slabs with your own hands, having previously prepared wood and Portland cement. Let's dwell on the properties of the material, consider the advantages and disadvantages of products, get acquainted with the nuances of technology.

What is a ready-made arbolite block

Chip blocks are a type of lightweight concrete. They are distinguished by a large-porous structure and a filler, which is used as wood shavings. Standard products have the shape of a rectangular parallelepiped with dimensions of 0.5x0.3x0.2 m. Block products are also produced with other dimensions corresponding to the dimensions of the molding box. Along with blocks, arbolite products are produced in the form of plates, to increase the strength of which reinforcement is performed.

Wood concrete includes the following components:

• wood filler in the form of chips of certain sizes;
• special active additives with chemical components;
• binder based on Portland cement M400;
• water, providing the plasticity of arbolite solutions.

Chip blocks are characterized by a large-pore structure

One of the conditions for obtaining high-quality material is uniform mixing of ingredients. First, the mass of each type of feedstock is determined depending on the required amount of solution. Then the weighed components are mixed and the next step is performed - filling the formwork boxes with mortar. To ensure the increased density of the blocks, the mixture is compacted in the molds. It is easy for developers manufacturing wood concrete to master this method of producing wood concrete.

Solid walls are built from arbolite blocks and internal partitions are erected in low-rise buildings:

• residential buildings;
• economic objects;
• industrial buildings.

Blocks and slabs are produced from the arbolite mixture, which differ in specific gravity and functional purpose. The margin of safety and the specific gravity of the wood concrete are connected by a direct proportion. More dense products are superior in terms of strength characteristics to blocks with reduced density.

Arbolite is classified into the following types:

• material with a density of up to 500 kg / m3, used for insulation of various types of building structures;
• structural products with a specific gravity of 500-800 kg / m3, which is used for the construction of load-bearing walls.

The use of wood filler and the coarse-mesh structure of the wood concrete mass do not allow the material to be used under heavy loads. You should make sure of the quality of the material when purchasing wood concrete for the construction of a private house. High-quality raw materials are not always used and the working mixture is saturated with liquid glass, which reduces hygroscopicity.

The main performance characteristics of wood concrete blocks

When planning to make blocks or wood concrete slabs with your own hands, you should familiarize yourself with the properties of the building material.

The performance of the material depends on the following factors:

• quality of raw materials;
• the proportions of the components in the solution;
• meeting the requirements of the technological process.

Main characteristics:

• density. Depending on the density of the raw materials used and the specifics of the manufacturing technology, the specific gravity of the material varies in the range from 0.5 to 0.85 t/m3;
• strength. It characterizes the ability of a material to perceive compressive loads. The load capacity for structural materials is B1.5-B3.5, and for heat-insulating materials - B0.35-B1.0;
• thermal conductivity. The ability of wood concrete to conduct heat is expressed by the coefficient of thermal conductivity, which increases from 0.09 W / m ° C for heat-insulating materials to 0.14 W / m ° C for structural blocks;
• frost resistance. The resistance of the material to the effects of temperature changes depends on the moisture content of porous wood concrete, which is able to maintain integrity during cyclic freezing;

Wood concrete is a high thermal insulation material

• moisture absorption. The material is characterized by increased hygroscopicity associated with capillary filling of wood filler with moisture. In the process of saturating the wood concrete with moisture through the air cells, the volume of the material increases by 1.5 times;
• shrinkage. The ability of the material to change the initial volume depends on the initial moisture content. The process of size reduction finally stops a couple of months after the blocks are made;
• fire safety. Despite the wood chips inside the wood concrete blocks, the blocks are included in the group of slow-burning materials. Arbolite material belongs to the products of group G1;
• vapor permeability. The porous array of arbolite slabs does not create obstacles for steam escaping from the room, which helps to maintain a comfortable microclimate inside the building.

Important characteristics of wood concrete products also include soundproofing properties, due to which the material prevents the penetration of external noise into the room. In terms of sound absorption, wood concrete surpasses traditionally used materials - brick, wood and.

Wood concrete building blocks - advantages and disadvantages of the material

Wood concrete is gradually gaining popularity in the construction industry due to its serious advantages:

Wood concrete surpasses traditionally used materials in terms of sound absorption

• reduced thermal conductivity. In buildings built from arbolite blocks, the temperature favorable for living quarters is maintained all year round. In addition, due to the reduced thermal conductivity, heating costs are reduced;
• sufficient margin of safety. With a compression force of 5 MPa and a bending load of 1 MPa, the material is not destroyed. Due to the strength of the material, arbolite products gradually restore their shape and original dimensions;
• resistance to deep freezing. Manufacturers of wood concrete blocks and slabs guarantee the frost resistance of products. Tests confirm the preservation of the performance characteristics of the material after 40-60 cycles of intensive cooling, followed by a sharp settling;
• ability to reduce noise exposure. The soundproofing characteristics of wood shavings used as a filler make it possible to create favorable conditions for those living in the room by absorbing external noise;
• reduced weight with increased volume. Using light and voluminous blocks of wood concrete, it is easy to quickly build the main walls of the house. The reduced mass of block material can significantly reduce the load on the foundation;
• harmless to health and the environment. The manufacturing technology of wood concrete products involves the use of environmentally friendly raw materials. The absence of harmful emissions from wood concrete confirms the harmlessness of the material to others;
• ease of use. Arbolit is easy to cut into blanks of the required size using an improvised tool. Problematic situations when cutting material and forming channels in it are excluded. In addition, a reinforcing mesh is not required for plastering wood concrete;
• maintaining original dimensions under load. Due to the low shrinkage of wood concrete blocks, not exceeding 0.6%, the likelihood of cracking on the walls of the building is reduced. The dimensions of the block material after being removed from the molds and dried are preserved;
• affordable price. The low cost of the material is ensured by the use of cheap waste that accumulates at woodworking enterprises in the process of manufacturing various products;

Wood concrete is harmless to health and the environment

• durability. Despite the fact that wood concrete has recently gained popularity in the construction market, it is a building material with a long service life. Safe operation of wood concrete structures is guaranteed for up to half a century.

Arbolit is in demand in the construction industry due to a set of advantages. After analyzing the shortcomings of wood concrete, we get a complete picture of the characteristics of the building material.

So, the weaknesses of wood concrete:

• instability of product dimensions. Increased dimensional tolerances are associated with the use of molds by different manufacturers that differ in size. To avoid the increased consumption of the plaster composition associated with dimensional deviations, it is possible to purchase blocks from one supplier;
• irreversible changes in the structure of wood concrete during intense heating. And although open fire does not cause ignition of wood concrete products, due to the high temperature associated with sudden heating, chips smolder. This significantly reduces the strength of the material;
• tendency to absorb moisture. Due to the increased hygroscopicity of the wood concrete, accelerated moisture saturation of unprotected walls occurs. The surface of the material needs to be plastered on the outside and inside of the building. It is also necessary to waterproof the foundation with which the arbolite blocks come into contact.

Other disadvantages include:

• the possibility of development of microorganisms due to the reduced concentration of lime;
• the need for additional insulation of wood concrete, which is easily blown;
• characteristic odor associated with the introduction of chemical reagents into the material;
• block damage by various rodents showing interest in it.

Having decided to make wood concrete slabs with your own hands for building a house, get acquainted with the advantages of the material and carefully analyze the disadvantages.

Due to the complex of advantages, wood concrete is widely used in construction.

How to make wood concrete slabs with your own hands

The answer to the question of how to make wood concrete blocks with your own hands is of interest to many developers. For the manufacture of products should:

• deal with technology;

For the industrial production of wood concrete, a vibrating platform will be required, which allows the production of blocks of increased density.

Preparation of wood chips for the production of wood concrete blocks

The composition of the working mixture and the proportions of ingredients

Despite the simple recipe for the preparation of wood concrete and the availability of raw materials, attention should be paid to quality issues.

The filler, which is used as sawdust, shavings or wood chips, requires special preparation:

• cleaning from foreign inclusions;
• crushing to sizes not exceeding 0.5x1x4 cm;
• drying for two to three months;
• lime treatment to prevent decay.

A lime mortar of 15% concentration is introduced in an amount of up to 500 liters per cubic meter of chips. Soaking woodworking waste is carried out with regular mixing of the material. The process takes no more than one week. During this period, the sugar content in the wood decreases, which reduces the likelihood of decay. It is allowed to use purchased raw materials or grind wood waste at home using a crusher.

In addition to wood chips, for the manufacture of wood concrete you will also need:

• cement brand M400 or M500. Do not use cured material. Fresh cement is needed, which crumbles easily. The strength of blocks and slabs depends on the quality of the binder;
• special additives that reduce moisture absorption and prevent the development of microorganisms. The technology provides for the possibility of using slaked lime, calcium chloride, liquid glass and alumina.

The necessary plasticity of the wood concrete mixture is provided by introducing water absorbed by the filler.

Do-it-yourself arbolite blocks

To prepare a cubic meter of arbolite solution, you will need:

• chips in an amount of 200 to 300 kg;
• cement, the weight of which is 250-350 kg;
• mineralizing additives - 8-12 kg.

Depending on the percentages of the ingredients, the density of the blocks changes.

How to make a mold for wood concrete blocks with your own hands

To pour the solution, you need a form for wood concrete blocks. It is easy to make it with your own hands using various materials:

• moisture resistant plywood;
• sheet metal;
• planed boards.

The box design is simple. This is a collapsible container in which there is no bottom, and there are carrying handles. The internal dimensions of the form are determined by the dimensions of the blocks.

Technology requirements for the manufacture of the mixture

Independent production of blocks is popular today. It allows you to reduce costs. The craftsmen who make it will easily master the technology for the production of wood concrete.

It includes the following steps:

1. Drying wood chips.
2. Crushing wood to the desired size.
3. Chip mineralization by soaking.
4. Weighing the feedstock and loading into the mixer.
5. Thorough mixing of components.
6. Pouring the prepared mixture into molds.
7. Sealing molded products.
8. Settling products for a week.

Historical data

The first wood concrete blocks appeared in the thirties in Holland. They include chemicals, cement and wood chips. For eight to ten years, the fame of this material spread throughout Europe. It was actively used in the Soviet Union.

In the sixties, more than a hundred factories for its production were opened in the USSR. Residential buildings, technical rooms, scientific facilities in Antarctica were built from wood concrete. During perestroika, some factories ceased their activities, the rest changed their production profile. Arbolite raw materials were no longer produced and used.

A few decades ago, blocks reappeared on the building materials market. Now they are actively used in the construction of private houses and other buildings.

In this video you will learn how to make wood concrete blocks in two minutes:

Features of wood concrete

Arbolite is a material consisting of sawdust and large-cell concrete. It is produced in the form of a slab or block, as well as a liquid mixture (it is poured into the formwork during construction). According to official standards, the composition of the blocks includes the following materials:

• wood chips of a certain size;
• calcium chloride, lime, water glass and alumina sulfate;
• water;
• cement.

The dimensions of the chips do not exceed 25 mm in length, 10 mm in width and 5 mm in thickness. Do not use shavings, sawdust or straw.

Although using sawdust, another building material is made that differs in characteristics and composition.

Some manufacturers sell low quality material

Advantages and disadvantages

Wood material is easy to process with a manual and mechanical saw. Nails, self-tapping screws and dowels are firmly held in blocks without emptiness. Other advantages of wood concrete:

• low thermal conductivity;
• low weight, which facilitates transportation;
• high soundproofing performance;
• environmental friendliness;
• elasticity and strength, which do not allow the material to crack under impact and stress;
• steam penetrates into the structural cells, which allows the blocks to breathe;
• it is easy to apply paint, putty or other finishing material on a porous surface.

All this tempts craftsmen to make wood concrete blocks at home.

Although wood concrete has some disadvantages:

• holes in the material will not protect the room from moisture, so it must be covered with a layer of waterproof plaster;
• the blocks have a fuzzy shape, it takes a long time to level the walls;
• some stores offer low-quality wood concrete, in the production of which small chips or reeds were used.

Ready-made wood concrete has a high cost, because of this, home-made material has become popular.

Do-it-yourself arbolite blocks:

Production conditions

The factories produce two types of wood concrete - heat-insulating and structural. The first type is used for warming finished structures, the second type, due to its high density, serves as the main material in the construction of load-bearing walls. Wood concrete does not ignite, quickly becomes saturated with moisture, but dries instantly. Hollow blocks are used in the construction of rooms inside which there is steam or water. The material removes excess moisture from the building.

In the conditions of factory production, the technology for manufacturing blocks is as follows:

• waste wood materials are crushed in a crusher, leaves and bark are removed from the mixture;
• the amount of chemicals depends on the type of wood, they are mixed with water;
• chips are poured into a concrete mixer with a heated water mixture;
• then cement is added and mixed for twenty minutes;
• the finished mixture is poured into molds, rammed with a press or by hand;
• formwork is removed and carbolite is dried.

When tamping, a vibropress is used. The density of the blocks depends on the size of the chips and their number in the solution.

Independent production of wood concrete

Due to the lack of special equipment, it will be possible to make blocks of wood concrete of low density with your own hands. They are used for wall insulation. It will take a very long time to sort out and clean chips from debris manually, and their size will not be the same.

In advance, you need to prepare a concrete mixer and an injection mold. The mixer must be auger, gravity will not allow you to create a homogeneous solution. Suitable forms for do-it-yourself arbolite blocks are plywood or metal boxes with partitions. It is easier to make containers with notches from plywood, which are necessary for creating hollow blocks. Particular attention is paid to proportions. Do-it-yourself arbolite blocks are calculated in kilograms, equating a liter of water to 1 kg.

Production of wood concrete blocks:

The recipe for wood concrete suitable for the construction of country houses and homestead buildings:

• the chips are soaked in slaked lime for three hours (10 shares of water are added to a part of the alkali), the raw materials are thrown into a sieve;
• pour the wood into a concrete mixer and fill it with water, the proportions are 4 volumes of water per three parts of the chips;
• then add liquid glass in a volume of 1% of the total mass, pour 4 shares of cement and knead until smooth;
• forms are lubricated with used oil, filled with a solution, compacted and allowed to brew for a day;
• after that, the blocks are removed and dried for a week in an open area.

For the manufacture of blocks, tools will be required, for example, a concrete mixer

You can immediately make wood concrete with cladding. When pouring into molds, leave 5 cm to the top, fill the free space with colored plaster or crushed gypsum tiles. After drying, the walls are trimmed with blocks.

The availability of suitable raw materials, free time and equipment enables developers to make wood concrete themselves. A woodworking enterprise located nearby will allow you to make a business in the production of wood concrete.

Arboblock, do-it-yourself arbolite block from a to z:

Wood concrete is a unique building material, ideal for the construction of walls, lintels, load-bearing structures. In the manufacture of blocks and slabs, sawdust, shavings with wood chips, cement and water, as well as other components are used. Cement serves to protect wood waste from external biological and atmospheric influences. Impact-resistant, crack-resistant and durable blocks are obtained. Such a building material has the properties of stone and wood, excellent thermal insulation properties, fireproof, does not rot, unlike wood. In the article we will tell you how to make blocks of wood concrete with your own hands.

Arbolite was popular in the second half of the last century. Using foreign experience, Soviet scientists, together with manufacturers, developed the optimal composition of the material. Houses were built from wood concrete blocks, which have retained their good condition even today. This is proof of the fact that wood concrete is characterized by excellent performance properties.

Arbolit is considered sawdust concrete, for its manufacture only high-quality cement is required, it is mixed with fine wood chips, shavings and sawdust. It is important to observe the dimensions of the filler, they should be approximately 5 mm thick and 25 mm long.

All wood fillers are first passed through the crushing mechanism, and then the mass is mixed with cement. The sugar contained in organics leads to swelling of the material, therefore, chemicals in the form of calcium chloride and aluminum sulfate must be added to organic waste to neutralize sugar. When making blocks yourself, wood waste should be kept outdoors for several months.

The manufacture of wood concrete blocks should begin with the processing of wood filler. To do this, crushed wood mass must be poured with water and gently mixed. To decompose sugar, it is recommended to keep wood waste in a solution of lime for about 3 hours. After soaking in a solution of lime, organics are mixed with cement in a concrete mixer until a homogeneous mass is obtained, no lumps should remain. It is necessary to take the components in the following proportion: 4 parts of water, 3 parts of cement and wood chips and sawdust. When squeezed in a fist, the finished mass should take the form of a lump, but it will turn out a little crumbly.

What advantages does

• After hardening, wood concrete can be easily processed: sawed, drilled, adjusted in various ways to the required size.
• The production technology is very simple and takes very little time.
• The material lends itself to any finish: it adheres well to plaster and concrete, it can be lined with bricks, sheathed with drywall.
• Blocks retain heat longer than bricks.
• Arbolit is not subject to fungal diseases.
• It is characterized by frost resistance, durability and reliability.
• It is light in weight and easy to transport.
• Possesses environmental friendliness.

Block production

The finished mass with a wood base is used to make blocks for building a house. To create blocks from wood concrete, it is necessary to prepare molds from wooden boxes of the right size, in which the bottom must be removable. To make it easy to take out the finished blocks, you can sheathe the boxes on the inside with pieces of linoleum or film. The mass is laid in prepared forms in layers in 2-3 stages, each layer should be carefully compacted. To increase strength and resistance to atmospheric phenomena, the blocks are lubricated from the outside with a cement solution. Blocks are dried in molds for more than a day so that the mass can harden. Then the blocks must be moved under a canopy, because they can dry out and crack under the rays of the sun.

You can buy a machine for the production of wood concrete, it is inexpensive. Professional equipment includes machines, concrete mixers and tamping presses. If you want to buy blocks, the price for them is affordable - about 50–60 rubles per block.
