Block wall: characteristics, reviews. Concrete wall blocks

Block wall - a modern material that allows you to build strong walls in a short time. Therefore, today he is a leader in the construction of any structures, including country houses and cottages.

What are wall concrete blocks?

Concrete wall blocks are a durable material, but it has low heat efficiency. Therefore, during the construction of a residential house, they are put together with a heater. The latter can be facing brick, decorative stone, plaster and the like.

Typically, the standard size of the blocks is 20 x 20 x 40. These parameters are optimal for convenience in the laying of this material, and also allow to finish the object in a short construction time.

Due to its voidness, the wall block allows to carry out any design decision. With their help it is easy to erect walls, and also quickly, precisely and qualitatively to put corners.

Types of concrete wall blocks

In the modern construction market, you can find a large amount of material for the construction of private houses, cottages, garages and other structures. The most optimal option, as we have already mentioned, is the wall block. Let's now try to understand the concept of "concrete wall blocks."

This material is divided into two categories:

• Hollow blocks (those that have through or blind holes);
• Full-bodied blocks (those that have no voids).

If we compare these two species, then solid blocks are used during the construction of a multi-storey building. This is due to their greatest strength. For the erection of a single-storey house, hollow blocks can also be used. But if a greater load is planned for this or that wall, in this case the voids of the block are filled with mortar or concrete.

What should I pay attention to when choosing concrete blocks?

As a rule, when a consumer chooses wall blocks, prices are the main criterion for his final choice. Unfortunately, buyers are neglecting technical indicators, trying to save on housing construction ..

In addition to the hollowness, about which we spoke above, it is necessary to pay attention to the frost resistance of the material. This characteristic is indicated by the letter F. When buying concrete blocks, it is necessary to take an interest in this indicator. It can vary from F15 to F200.

Frost resistance of the blocks implies the ability to maintain its primary characteristics (in this case, strength) during significant temperature and moisture changes. Many of you probably saw that the wall or corner of a newly built house began to crumble or crumble in the spring. This indicates that the frost resistance is very low. Thus, experts recommend not to save and choose the material and the largest number of F.

Reviews of the concrete wall block

Today, the greatest demand among builders is concrete wall blocks. Prices for this material are the lowest (from 38 rubles per block), in addition, concrete blocks have a number of positive characteristics that sound in customer reviews.

First, concrete is a non-combustible material. He perfectly resists even the open fire.

Secondly, concrete blocks have high sound insulation, which is noted in the reviews. Thus, from them it is possible to build any structures.

Thirdly, modules and parts from any other materials can be attached to the wall of concrete blocks.

Fourthly, this material is considered environmentally friendly. It is believed that the concrete wall block "breathes", so in the future "living" house you will feel comfortable.

And the last important moment is a good thermal insulation. Although the opinions of experts recommend that the walls of such a block still be covered with brick or other material.

According to this, it can be concluded that the concrete wall blocks are an excellent option for building an inexpensive quality country house.

Other types of wall blocks

Thanks to the technical progress today in the building stores there were all kinds of materials for the laying of walls. The concrete concrete wall blocks did not stop there. Over the last decade of their varieties has become much more. All of them differ in their characteristics, as well as in the price category.

So, in addition to concrete, today it is worth noting such wall blocks:

• Aerated concrete;
• Gas silicate;
• Expanded clay;
• Polystyrene concrete;
• Foam blocks.

All these materials are also in great demand in the modern construction market, as well as concrete blocks. But still, they have more positive moments. First of all, it concerns the greater thermal conductivity and sound insulation. Secondly, they all fit on a very thin layer of solution or special glue, which makes the process of their laying less labor-intensive. In addition, it should be noted that all this material has ideal angles. Therefore, in order to drive an ideally flat wall, it is necessary to make plumb bows and adjust everything for them.

It is also worth adding that after the construction of the house, the internal walls of aerated concrete or silicate, for example, do not have to be plastered. In order to give them a smoothness, simply apply several layers of putty.

The only disadvantage of these types of block is the cost. The price of this material is high. Therefore, not everyone can afford to buy them.

Production of wall blocks

For each type of blocks - its own way of production. Foam concrete and gas silicate are blocks of cellular wall. During the production of foam concrete, cement, water, sand and foam are used. As for gas silicate, it consists of quartz sand, water, cement, lime and aluminum crumb (it is needed as a gasifier).

After the formation of any wall blocks, they need to allow time to dry. If the foam concrete dries naturally, then for the gas silicate blocks, the conditions of the autoclave are necessary.

The dimensions of the wall blocks of all these types can differ significantly. In addition, this applies not only to different, but also blocks of the same material. For example, the parameters of aerated concrete blocks can be as follows: 600 x 300 x 100, or the following: 600 x 200 x 400 mm.

Which material is better to build a house?

The modern production of wall blocks is so diverse that sometimes people do not know what material to choose in order to build a country house. Based on the above characteristics, you need to choose, given how many floors you want to build and in what climatic zone you live. And of course, you need to build on your financial resources. Do not get hung up on one material, perhaps you will find it a more accessible analog.

Remember that you can always choose the best option in this or that situation. This also applies to the material for the walls of your country house.
