In the modern world, construction is developing at a rapid pace, thereby increasing the demand for materials. Cellular concrete has become popular in the domestic market. At one time, products were widely advertised, and the demand for them is now great.
Manufacturers of
aerated concrete say that it is universal, but they always ignore the fact that
aerated concrete blocks also have disadvantages. In order to better understand the properties of the product, consider what cellular concrete is. This is an artificial material that has mineral binders and silica fillers. Inside the blocks are pores. Its derivatives can be called foam concrete and aerated concrete. Foam concrete is based on foamed sand-cement mixture. Aerated concrete is obtained by adding aluminum powder and sand to a lime-cement mortar.
Advantages of the material:
- fire resistance;
- environmental friendliness;
- high thermal insulation properties;
- light weight;
- vapor permeability;
- frost resistance;
- ease of handling;
- cheapness.
The most comfortable houses are built from Aeroc material (aerated concrete). Such buildings are absolutely protected from all the troubles that await residents of country houses - a defeat by fungus, insects, ultraviolet radiation and so on. Environmentally friendly material does not harm the environment.
However, professionals are not often taken to work with materials such as aerated concrete blocks, the flaws of which they know as well as the virtues. Not any cellular concrete is suitable for the construction of a building, especially its load-bearing elements. Masters try to work with aerated concrete brand D500.
Experts know that aerated concrete blocks have the following disadvantages:
- poor waterproofing;
- fragility of the material;
- insufficient bending resistance (fragility).
Aerated concrete houses should be built by professionals. Because, if mistakes were made when pouring the foundation, cracks will go throughout the house. For example, the foundation must be necessarily monolithic and strip, and not everyone can afford the extra expenses when pouring a large amount of concrete.
For fifteen years in the west they have been building houses from blocks that have different characteristics compared to, for example, brick and wood. When building houses from foam concrete , special equipment is not required.
Builders use
aerated concrete blocks for country
houses, the shortcomings of which they always take into account. For example, products having insufficient density cannot be used for
load-bearing walls. It is necessary to apply reinforcement in multi-story construction. It should be borne in mind that no more than 3-5 floors are built from blocks.
Aerated concrete blocks require special fasteners, so experts prefer not to work with them, despite their high quality and seemingly inexpensive cost. The fact is that after a complete calculation of the required material, its cost rises significantly.
Aerated concrete is still very popular in construction. It is necessary not only to withstand the entire technological process of building a house, but also to acquire material manufactured in industrial conditions, and not by private companies.
