Wall block is a modern material thatallows you to build strong walls in a short period of time. Therefore, today it 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 materialhowever, it has a low thermal efficiency. Therefore, during the construction of a residential house, they are put together with insulation. The latter may be a facing brick, decorative stone, plaster and the like.
As a rule, the standard block size is 20 x 20 x 40. These parameters are optimal for ease of masonry of this material, as well as allow you to complete the object in a short construction time.
Due to its voidness, the wall block allows you to perform any structural solution. With the help of them it is easy to build walls, as well as quickly, smoothly and accurately put corners.
Types of concrete wall blocks
In the modern construction market can be founda large amount of material for the construction of private houses, cottages, garages and other structures. The best option, as we have already mentioned, is considered a 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 non-through cavities);
- corpulent blocks (those that have no voids).
If we compare these two species, the full-bodiedblocks are used during the construction of a multi-storey building. This is due to their greatest strength. Hollow blocks can also be used for the construction of a one-story house. But if a large load is planned for this or that wall in the future, then in this case the block voids are filled with mortar or concrete.
What should I look for when choosing wall concrete blocks?
Typically, when a consumer chooses a wallblocks, prices - this is the main criterion for its final choice. Unfortunately, buyers neglect the technical indicators, trying to save on housing construction ..
In addition to the hollow we talked aboutabove, it is necessary to pay attention to the frost resistance of the material. This characteristic is denoted by the letter F. When buying concrete blocks, you need to take an interest in this indicator. It can vary from F15 to F200.
The frost resistance of the blocks suggests the abilityto retain its primary characteristics (in this case, strength) during significant changes in temperature and moisture. Many of you have probably seen that the wall or the corner of a newly built house after a few years in the springtime began to crumble or crumble. This suggests that the cold resistance rate is very low. Thus, experts recommend not to save and opt for the material and the highest number F.
Reviews of concrete wall block
Today the greatest demand among buildersare concrete wall blocks. Prices for this material are the lowest (from 38 rubles per 1 unit), moreover, concrete blocks have a number of positive characteristics, which are heard in customer reviews.
First, concrete is a non-combustible material. He perfectly resists even 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 fastened to the wall of concrete blocks.
Fourth, this material is considered environmentally friendly. It is believed that the concrete block wall "breathes", so in the future, "living" house you will feel comfortable.
And the last important point - good insulation. Although the reviews of experts recommend that the walls of such a block anyway obkladyvat brick or other material.
According to this, we can conclude that the concrete wall blocks - a great option for building an inexpensive high-quality country house.
Other types of wall blocks
Благодаря техническому прогрессу сегодня в building stores appeared all sorts of materials for laying walls. It was not limited to concrete wall blocks. Over the past decade, their varieties have become much more. All of them differ in their characteristics, as well as price category.
So, in addition to concrete, today it is worth noting such wall blocks:
- aerated;
- gas silicate;
- expanded clay;
- polystyrene concrete;
- foam blocks.
All these materials also enjoy greatdemand in the modern construction market, as well as concrete blocks. But still, they have more positive points. First of all, it concerns greater thermal conductivity and sound insulation. Secondly, they all fit on a very thin layer of mortar or special glue, which makes the process of their laying less time consuming. In addition, it is worth considering that all this material has perfect angles. Therefore, in order to drive a perfectly flat wall, it is necessary to make plumb lines and fit everything under them.
It is also worth adding that after the house is builtinterior walls of aerated concrete or silicate, for example, plastering is not necessary. In order to give them 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
Для каждого вида блоков - свой способ production. Foam concrete and gas silicate are cellular wall blocks. During the production of concrete used cement, water, sand and foam. As for gas silicate, it consists of quartz sand, water, cement, lime and aluminum fine crumb (it is needed as a blowing agent).
After forming any wall blocks, they must be allowed to dry. If foam concrete dries out naturally, then autoclave conditions are necessary for gas-silicate blocks.
Dimensions of wall blocks of all these types canvary significantly. In addition, this applies not only to different, but also blocks of the same material. For example, the parameters of aerated concrete blocks may be as follows: 600 x 300 x 100, or as such: 600 x 200 x 400 mm.
What material is better to build a house?
Modern manufacture of wall blocksso 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, taking into account how many floors you want to build and in what climate zone you live. And of course, you need to build on your financial assets. You should not dwell on one material, perhaps you will find a more accessible counterpart to it.
Remember that you can always choose the best option in a given situation. This also applies to the material for the walls of your country house.
