House of concrete blocks: simplicity, cost, reliability

Building

Hollow concrete blocks are an excellent building material, both for private housing, and for planned construction. This material has appeared on the market relatively recently, but has already gained popularity due to its high qualities.

Block advantages

Immediately it should be said that due to its versatility and relative cheapness, this material was so widespread that in Europe it accounts for about 30% of objects in the housing sector.

Note! In Russia and the states adjacent to it, this proportion sometimes reaches 90% of the total volume of buildings intended for housing.

It is worth listing the main advantages.

Thermal insulation

Thermal insulation qualities of this material are at the highest level.

Suffice it to say that concrete blocks retain heat 2.5 times better than the same brick.

Firstly, it is connected with the structure of the concrete itself, since there are so-called cells in it, and cold air is trapped in them.
And secondly, when building an object from ready-made blocks, instead of the usual solution, a special glue is used for the laying of aerated concrete blocks.

An example of a block that can show excellent insulating qualities

Thanks to the use of glue, and not ordinary cement mortar, the thickness of the seams does not exceed 3 mm. Accordingly, the cost of heating such a building will be several times lower. This is especially true when building in a zone with a temperate and cold climate, where such an indicator as thermal conductivity plays a huge role.

physical characteristics

In the previous paragraph, we compared blocks with bricks. If we continue this comparison, the strength of the finished block is not inferior to a brick.

In addition, you can note:

Long operation of a design. All buildings of this type are designed for service life in excess of 100 years.
Lightweight design. The material from which the finished blocks are made is 5 times lighter than ordinary concrete. This helps to avoid the construction of a powerful and deep concrete foundation, and also allows you to build a house with your own hands.
Prefabricated units are an excellent sound insulator on their own.. Due to its porous-cellular structure, the structure poorly conducts sound waves, thus avoiding the additional cost of sound insulation of the room.
This is a fireproof building material.. Fire safety of such buildings is at the highest level.

Construction features

Immediately it must be said that the relative simplicity of erection of structures allows building many buildings practically in an independent mode. The fact is that concrete blocks for the construction of a house with their large sizes differ from each other in parameters by a maximum of 2 mm. This allows you to build an object rather quickly.

Concrete blocks with exact dimensions and proportions, nothing needs to be adjusted when laying

For example, a small-sized house can be built in 2 months.

In addition, in construction work with blocks, the following points can be noted:

The small thickness of the walls again makes the whole structure even lighter without sacrificing strength characteristics and thermal insulation properties.
Lightness in the interior and exterior walls. The walls of the finished blocks do not require additional preparation before the conduct of painting work. Cable routes are easily laid in the walls themselves, air ducts and other engineering communications are arranged.
Projects of houses made of concrete blocks allow the possibility of redevelopment, if the need arises.
Such walls are conveniently reinforced to bring the design of additional strength.

Note! Walls of this material are usually reinforced both vertically and horizontally.

Classification and size

There are 2 main classifications, according to which the finished blocks are distinguished among themselves.

Display it as a table.

First classification	It is a division into marks depending on such characteristics as compressive strength. According to this classification, the brand of concrete blocks range from 50 to 300.
Second classification	According to the second classification, there is a division into marks, depending on their ability to tolerate low ambient temperatures without compromising strength characteristics. By their frost resistance, the finished blocks are divided into brands from F15 to F200.
Dimensions	As for the dimensions of the block itself, the following parameters are most often encountered: Length - 39 cm, height - 19 cm, width - 19. As for the width, this characteristic can vary, and sometimes the width is 24 cm, and in some cases all 29 cm

Note! The instruction states that for the construction of low-rise buildings, it is necessary to use material of grade 75 and higher.

From the above facts, it becomes clear why concrete blocks occupy one of the leading places on the building materials market, and its popularity is steadily growing. It is perfect for building buildings in a harsh climate.

Frost-resistant unit that can be used in any climate zone

And its low weight, more than adequate price and speed of erection of structures, make ready-made blocks an excellent alternative to many other building materials, completely not inferior to them in quality and strength.

Conclusion

As can be seen from the stated facts, concrete blocks in the construction of residential premises may well be used, both from the point of view of the technological approach and from the point of view of functionality. And the video in this article will demonstrate how you can work with them.
