It is known that the search for optimal solutions for the construction of private houses is "imprisoned" in favor of saving and improving the home. But about the shortcomings of brick walls or concrete overlap with a miserable soundproofing is also known. But the appearance and promotion of available materials is still a little attention. The construction industry unwillingly reveals the secrets of forgotten ancestors: foam glass and arbolite. Want to fill your knowledge and direct a vector of creative activity in favor of arbolita?

Arbolit, what is this material?
The best material, incorporating the qualities of concrete and wood, is woodworking (sawdust concrete) or arbolite. According to the standard (GOST 19 222-84) "... arbolite is a kind of lightweight cellular concrete", which consists of wood chips (aggregate), high-grade cement (mineral binder from organic materials) and hardener.
Strict propaganda of saving resources of those times and the lack of innovative technologies, which now abound in construction, have created sawdust concrete. Cheap and angry! Call the novelty of this material is impossible, because in the golden Soviet times from the blocks of arbolite built polar stations and houses.
Forgotten for a while, the material reappeared on the horizon of the construction industry, but already in a new quality in the construction of suburban one-story houses and cottages. Do you want to know what changed in the shape of the arbolite of the 60's? Almost nothing, the same successful combination of excellent qualities of wood and improved properties of lightweight concrete from organic filler.
But a slow shot from the past worked unmistakably, and the charge hit the target exactly. Therefore, modern construction from arbolita can be called a "hit" of the century.
Why does such a simple material of wood chips and concrete attract attention so much?
Arbolit - structure, species
Wood chips for arbolite are the main component of the material, and we must give credit, cheap and low-cost. Wood chips do not require additional processing during production. With the industrial production of arbolite in the composition use any wood chips.
Therefore, ready blocks and panels from the arbolite are well subjected to machining: they are sawed, cut, drilled and chopped like a log. The surface perfectly holds the screws and nails, representing the pink dream of any home Master.
The characteristic surface structure of arbolite products is able to provide first-class adhesion to the traditional plaster layer and concrete surface, excluding additional reinforcement. Naturally, such stunning qualities are obtained due to technical characteristics.
Technical characteristics of the arbolite
Let's name the main characteristics of wood-concrete:
- density (average) from 500 to 850 kg / m³
- strength: at compression - 3,5 MPa; when bending - up to 1.0 MPa
- thermal conductivity 0.08 - 0.17 W / (m * C)
- sound absorption from 126 - 2000 Hz
- water absorption from 45 to 85%
- fire resistance 0,75 - 1,5
- biostability group -V
- shrinkage to 0.5%.
By the way, the prevailing opinion that the appearance of microorganisms or insects in the tree walls is erroneous. In products and houses from arbolita mold, fungi and insects are not planted. They simply have nowhere to go - all over the concrete.
Form and types of arbolite
Arbolitic products distinguish types and form of release.
The following types of arbolita are distinguished by density:
- heat-insulating (from 400 to 500 kg / m3)
- construction (500 - 850 kg / m3).
Thermal insulation material is used as a heater of arbolitic houses, and structural as a wall carrier material.
According to the presence of the texture of the outer layer, the arbolite is divided into a face block and ordinary wall building blocks. There are blocks for walls and partitions.
Depending on the indicator of the density of the material in the dried state, the argolite is labeled 5; 10; 15; 25; 35 and 50.
form of issue
According to the form of production of arbolite by industrial means, there is such a nomenclature:
- wall blocks (600x300x200 mm)
- partition blocks (400х190х190 mm)
- small-sized panels.
According to the presence of the texture of the outer layer, the arbolite is divided into a face block and ordinary wall building blocks.
Knowing the recipe and composition of the arbolite it is possible to produce blocks with your own hands.
How to make own blocks from the arbolta will tell Vladimir from the video.
From the varietal arbolite it is possible to erect one-, two-story private houses and other structures (baths, garages, fences and utility rooms).
Due to the fibrous wood structure of the arbolite, the flexural strength is high. By the way, this quality is not possessed by any other masonry material.
Arbolit houses
Arbolite products are lightweight construction, which makes it easier to lay a foundation when laying and building a house. For the house, it is possible to erect a shallow foundation to 1.5 m. When constructing walls, a 40 cm plinth will allow the subsequent laying of blocks from the arbolite.
The process of erection of walls does not differ from the installation of walls of brick or gas block, but additional insulation will not be required.
Blocks and panels from the arbolite have a classical geometry, so the masonry and erection of walls is done quickly.
Although the price of arbolite products is still quite high, but the practice of living in a country house confirms the practicality and comfort of a house from an arbolite. The only drawback of the arbolite is that the houses absorb moisture very much. Built houses are almost twice cheaper than from a beam, foam concrete and brick.
