In private and urban construction is gainingpopularity of new material - aerated concrete. The blocks made from it constantly occupy a leading position in the sales lists of specialized building stores.
This is primarily due to the fact that manyRussians are trying to acquire country houses and cottages. The need for aerated concrete blocks proves an increase in the volume of such construction. Sometimes demand exceeds supply.
The article will deal with aerated concrete blocks,technical characteristics, disadvantages and advantages of the material. After studying it, you will learn why aerated concrete blocks are so fond of country developers that you need to know when acquiring this popular building material.
Aerated concrete is one of the varietieslightweight cellular concrete. It is obtained by mixing aggregates (silica sand and lime) and various additives with water and a binder (cement). If you do not take into account the composition of additives, then this is a recipe for the manufacture of classical concrete. Aluminum powder is used as them in aerated concrete.
It is she who plays the role of the blowing agent whenmixing the whole mass. A huge number of bubbles, resulting in the preparation of the solution, during its solidification forms a specific porous structure, which is a distinctive feature of aerated concrete.
Low weight of aerated concrete blocks and not badstrength markedly distinguish them against the background of materials intended for the construction of walls. Real estate developers are attracted by good thermal insulation, noise insulation and fire resistance characteristics.
Aerated concrete blocks are produced in hugeassortment that allows builders to choose blocks of the desired size, shape and construct walls of any architectural configuration. Not the last argument in favor of the choice of blocks of aerated concrete are the timing of the construction of houses from this material. They are much less than the time spent building a brick house.
Aerated concrete is an environmentally friendly material and has no effect on human health. This results from the fact that for its production natural natural components are used.
With all its many advantages, aerated concrete blocks have a low, affordable price for many Russians. This undoubtedly affects the popularity of the material.
Certain disadvantages have aerated concrete blocks.Specifications indicate the material is breathable. This is due to its structure. During operation, moisture can accumulate in numerous pores, and this leads to local destruction of its integrity.
Buildings made of aerated concrete blocksrequire mandatory internal and external decoration with good waterproofing, eliminating the ingress of moisture into the material. This will greatly extend the operational life of the house.
Aerated concrete blocks do not have a high prismstrength like a brick or wood, so they are subject to the formation of cracks, to avoid this, there are rules and recommendations that must be followed when building a house.
Aerated concrete blocks, the price of which suitsMany Russians are becoming one of the most popular materials used in country construction. The cost of a cubic meter of material varies from 3250 to 4350 rubles. It all depends on the region where aerated concrete blocks are purchased.
Если сравнивать стоимость стен из кирпича, то она 30% higher than that of aerated concrete. The material has a small weight, so the construction of aerated concrete blocks saves considerable money, starting with the construction of the base of the house. For the building of aerated concrete does not require a strong base.
Due to its cellular structure, the materialbreathes, has excellent heat-saving properties. This can explain the comfortable environment in homes built from concrete blocks, significant savings in fuel costs.
The laying of aerated concrete blocks is facilitated by simplicity.their processing. Material can be drilled, sawed, prick. This work is done with simple tools available to every home craftsman. It is these qualities that allow builders to realize the most fantastic designs of architects; laying utilities does not cause much difficulty.
With a wealth of advantages, aerated concrete blockshave some drawbacks. Hygroscopicity is the main one. If we neglect the waterproofing of the walls of the blocks, they quickly collect moisture, which leads to their destruction.
Особенно надо следить, чтобы стена из aerated concrete blocks are not exposed to freezing. Therefore, building a house of blocks, you need to take this into account. The best way out of this situation is to constantly live in such a structure or maintain a constant temperature there, at which the freezing of the house is impossible.
Aerated concrete walls protect against moisture, covering themspecial mortar, veneering with wood, plaster and other suitable materials. Performing finishing work, we must remember that the presence of ventilation between the wall and the finish is necessary. Otherwise, all the work will be done in vain and only harm.
The laying of aerated concrete blocks has insufficientbending strength. Unlike wood, which easily carries significant shifts in the foundation, a wall of aerated concrete does not have this ability. The limit of its deformation is 0.5-2 mm / m. Exceeding these dimensions leads to cracking of the masonry, and in the worst case, to destruction.
When building a house of concrete blocks, there are a number of activities that prevent the formation of cracks on the walls:
The device slab or strip base of the house.
Masonry with reinforcement.
Creating ring straps.
Aerated concrete blocks are very popular in construction. Technical characteristics show that houses made of this material do not need a capital, weighted foundation.
Houses made of aerated concrete are suitable for seasonal andpermanent residence. In winter, it will take only 3-4 hours to fully heat the house; this is due to the fact that aerated concrete walls have less thermal inertia than buildings made of other materials. To the touch aerated concrete blocks are much warmer than traditional brick.
The blocks are large and accurategeometric shape, thanks to this, houses are made of such material quickly. The connection of blocks with glue guarantees high quality and quick laying. In the ratio of "aerated concrete blocks: price and quality," the latter prevails.
If you compare the cost of building a brickhouses and buildings of gas blocks, the latter is much cheaper. Savings are achieved due to the lower cost of building the foundation, walls, pay builders. When working with aerated concrete blocks, simpler tools are required.
One of the main advantages of the building of aerated concrete blocks, compared with wooden houses, is fire resistance.
Aerated concrete blocks (technical specificationsit is shown) - a material that has many advantages, but, as always, does not do without a spoon of tar. The building and the blocks themselves have some drawbacks. To reduce or get rid of them, there are special ways, performing which you can minimize the drawbacks of the material. As a result, at the end of construction there will be a solid house with a long operational period.
