Laying aerated concrete blocks and their technical

Building a house is troublesome and expensive. Every prudent owner wants to save and at the same time get a reliable warm building.

To date, this opportunity can provide blocks of aerated concrete. In this article we will examine their technical characteristics and installation technology.

General provisions

Cellular concrete is in fact not a novelty in the construction market and has been patented at the beginning of the last century. But he began to gain wide popularity precisely in our days because of the rise in energy efficiency requirements for residential buildings. Quartz sand, lime, water, cement and aluminum powder in the process of certain processing guarantee their observance and many more positive qualities:

Benefits

1. Relatively light weight.

From this we can distinguish two advantages at once:

• Lack of need for a strong foundation, which saves on pouring the base.
• The ease of lifting products in the case of the construction of more than one floor.

In comparison, for example, with a classic and well-known brick, it looks like this:

1. Ease of processing. Right on the construction site, you can use an ordinary hacksaw to give the block any shape you need. Such a time-consuming operation as cutting reinforced concrete with diamond circles is not required here.

1. High thermal insulation performance, thanks to which in a gas concrete house it will be cold in winter and warm in hot summer. In comparison with brick, it looks like this:

1. High level of frost resistance, no less than F So in the winter you can not worry about the integrity of the aerated concrete structure.
2. Excellent fire resistant qualities. Withstands temperatures up to +300 degrees Celsius, which is more than enough to withstand a household fire.
3. Ecological purity. By production only natural raw materials are used.
4. Lack of tendency to processes of rotting and corrosion.
5. Noise insulation. Allows you to isolate comfortably from the noise of the street.
6. Acceptable Compressive Strength, which allows to build structures of up to twenty meters in height using blocks of cellular concrete.

1. Affordable price. The cost of the products under consideration is significantly lower, again, of the same brick.
2. Long operational life.

disadvantages

In the world, unfortunately, there is nothing perfect, as is the case with aerated concrete.

Its use is overshadowed by the following qualities:

1. Relative fragility. A strong blow or fall from a high altitude may result in splitting the product.
2. Hygroscopicity. Such blocks absorb water very well, which can lead to their premature destruction.

Tip: it is recommended immediately after the erection of the walls of aerated concrete, put on them plaster. So you protect them from the harmful effects of excessive moisture.

Assembly work

The cost of laying concrete blocks even goes below the use of many other building materials, still remains significant. Therefore, it does not hurt to get acquainted with the intricacies of this technology.

Instructions for laying concrete blocks:

1. We prepare the following tools for the laying of aerated concrete blocks: trowel, bucket, hacksaw, rubber hammer, ordinary hammer, chisel, spirit level and plumb.
2. Knead the solution for laying aerated concrete blocks of cement and sand in the ratio of one to three.

Tip: It is recommended to use a construction mixer with a special whisk for mixing. This will greatly facilitate and speed up the task, as well as allow you to achieve maximum homogeneity.

1. We put a two-centimeter layer of mortar on the foundation.
2. After solidification, we cover it with a layer of roofing material to create a waterproofing.

1. Directly masonry of aerated concrete blocks starts from the corners. To do this, we install two blocks on both sides of it, preliminarily putting a cement mixture under them.
2. With the help of a plumb we expose the vertical of the corner lock from aerated concrete. At the same time it is convenient to level products by means of the rubber hammer.
3. Further from the corner lay out the first row. To do this, apply the solution to the roofing material and the end of each block. The horizontal is controlled using a spirit level; if necessary, we trim it again with a rubber hammer or an additional amount of the mixture.

1. With a chisel and a conventional hammer, we make centimeter grooves along aerated concrete sections, which are then filled with mortar and we place steel rods in them. This process of reinforcement of masonry of aerated concrete blocks, which must be carried out every four rows.

Tip: It is recommended to use an electric wall chaser to create the necessary recesses. So you can handle it much faster.

1. Laid out the bottom row, proceed to the next. It is important that the connecting seams do not coincide, that is, the upper blocks should be indented by about a third of the block. To do this, cut the first product.

1. Similarly, we build the entire wall. After solidification of the solution we make the necessary communications. It does not require such a time-consuming process, as diamond drilling holes in concrete, it will be enough ordinary pobeditsovyh nozzles.

Conclusion

Gas concrete – надёжный и очень тёплый строительный материал. Его использование позволяет достаточно экономно возвести уютное и комфортное здание. Монтажные работы при этом вполне выполнимы собственными силами.
