Before starting construction, all the necessary materials have already been selected and purchased. As a rule, they are well known and tested for centuries. But during the period of rapid development of technology, it is worth paying attention to the new building materials that have already managed to prove themselves well. One of them is aerated concrete (artificial stone).
Production
The manufacture of aerated concrete blocks is similar to baking bread: cement and ground quartz sand are kneaded in water, then crushed lime, gypsum stone and aluminum “powder” are added — the basis is ready. In a warm and wet chamber, it rises, turning into a “loaf”, which is later cut into several blocks. These blocks are placed in an autoclave stove, hardening them with water steam at a pressure of 9-12 atmospheres. Now the material is ready.
Advantages
To highlight the basic properties and advantages of aerated concrete, it should be compared with the most famous wall material — brick. The external walls of the building according to their thermal protection characteristics will comply with the requirements of SNiP, if aerated concrete 400 mm thick and a density of 500 kg/m3. If you take a brick instead of it, then in order to achieve the same thermal conductivity indicators, the thickness of the brick wall should be 640mm. At the same time, the weight of 1 m2 of aerated concrete wall will be 220-230 kg, which is three times less than the weight of the brick wall of the same area. As a result, for the foundation for a house with aerated concrete walls, it will be consumed half as much. After all, its cost is lower than the cost of a tree or brick.
Aerated concrete will accelerate the construction process. Wall blocks of this material are greater than a large brick, the finish does not require the use of facing brick, and this reduces the complexity of the masonry at times. Of course, aerated concrete is somewhat inferior to brick in strength, but no one is building a high -rise building from it. And a reliable, warm house for all families just a season — please! With proper installation, the service life of the finished wall is about 100 years.
Another important advantage of aerated concrete is fire resistance (the wall can restrain strong fire from two hours or more). In terms of qualitative characteristics, it exceeds the tree, t. To. all other things being equal (lightness, the ability of the material to “breathe”, ease of installation, good heat -insulating properties), aerated concrete is able to actively resist the effects of high temperatures.
The demand for aerated concrete is quite high. Experts are convinced that houses, which are based on such material, bring the construction of low -rise buildings to a qualitatively new level. Thanks to the special properties of aerated concrete, expressiveness and architectural freedom, efficiency and optimal environmental comfort are successfully combined. Do not be afraid of innovation, and then construction will not become a painful process, but the joy of amazing discoveries.
