Arbolit: what is it, what's it made of and where used Bashny.Net

Arbolit is a building material based on cement and wood chips that have good technical characteristics and differ in their properties from those of standard concrete and from opilkobetona.

Because the basis of the arbolit is chips, to its size and to the number of compounds used for the best, because it depends on quality and brand. Before using wood chips passes strict scrutiny. The most appropriate kinds of wood for the production of arbolita are pine, beech or spruce.





A major role in the quality of the material is even the time of harvesting late or early — it directly affects its final properties. The size of chips should not exceed 25 mm in length and 10 mm in width.





Astringent component in the arbolit is the cement brand below M300 not because of the brand depends on the strength of the finished material. To improve the connection of the components of the mixture to each other and its rapid solidification, using various additives, such as chlorides of potassium liquid glass. Wood chips and cement mix poorly, so the process of production of arbolita should go without disturbing the process. One of its important phases is a long and thorough mixing of both components.

 

Types of arbolit and its specificationsAt the moment are produced in two basic forms.:

• Insulating cement wood, with a density of about 500 kg/cubic m, As already clear from the title, this material is used as an insulating layer in the construction of interior partitions, which is not under load.
• Structural cement wood. Its density is much higher and can reach 800 kg/cu. m. This is because the amount of cement in it is much higher than the chips. Technical characteristics of such arbolita will be used in the construction of pillars and walls. To give it greater strength, perhaps reinforcing mesh or rods.

Arbolit is available in two types:

Blocks. This is a completely ready-to-use building material having certain geometric dimensions. Unfortunately, because of the peculiarities of arbolita its size may be error. Despite the fact that they are regulated by GOST, in fact, inconsistency can be very serious. This feature should be taken into account when designing and calculating the required material. Concrete blocks can have a U-shaped recess, and also to be large, medium or narrow. Monolith. Arbolit of this type are produced directly at the construction site immediately prior to laying. Batch after batch, you must use the fully. This method is most suitable for a thin insulating layer in the room. The advantages of arbolit

• Good insulating properties. The thermal conductivity of the arbolit is only 0.08 W, which is much better than concrete or brick.
• Fire safety while maintaining all the advantages of wood. Arbolit practically does not burn and emit heat with very little smoke.
• Water vapor permeability arbolita comparable only with wood. Inside of it will always be very comfortable microclimate. Arbolit is indispensable for the construction of saunas, baths and other premises with high humidity level.
• Good resistance to tensile loads. This is very important when seasonal soil movements when the walls of the house can start to "walk" and to crack.
• Frost. Arbolit is able to withstand temperatures down to -50° C. unfortunately, with the alternation of negative temperatures and high humidity the shelf life of the arbolit is significantly reduced.
• Light weight. During the construction of arbolit it is possible to do without Foundation, as the blocks do not have a big load on the ground.

Disadvantages arbolita

• Low strength. From arbolit allowed to build only low-rise buildings or interior walls.
• The durability of the material depends on the quality of its constituent materials. Unfortunately, the market can meet the arbolit made from low quality raw materials with violation of technology. These blocks will last long.
• Arbolit, manufactured according to GOST, has a cost comparable to the cost of foam.
• In the construction of houses from arbolita necessarily require external finish of the walls, because errors in the size of the blocks, seams to be not quite accurate, and the material is not too decorative in appearance.

 Technology.the process is quite simple, so the arbolit it is possible to create, for example, for the construction of small outbuildings. The only drawback is slow curing of the composition, which the start of construction will have to wait at least three weeks.

And finally, some more information. The structure of arbolita can be built in any climate and in any soil. Wood concrete building weight eight times lighter than brick and is three times — homes built of foam. The scope of arbolita in residential construction — erection of two-storey houses and fences, baths, garages, outbuildings. As you can see, the range of possibilities arbolita is very large. published
