As building material, the origin of the brick goes deep to antiquity. At first, the material was called plinf, from the Greek PLINTHOS — brick. The first bricks were square with sides 300 — 600 mm 30 — 90 mm thick. The mass of brick was made of clay and resin. For many years, the cheests brick began to be replaced by a more durable and reliable ceramic material, which turned out to be firing cheests. And until today, the global spread of brick has made it an integral part of the construction.
Construction brick has always been used in structures that can withstand heavy loads, as well as during the construction of responsible and loaded structural elements.
Everyone knows that construction brick is full and hollow. For the foundation, full -bodied bricks are often used. Because such material has high technical indicators: frost resistance, strength, which is important for foundations.
The price of brick as
When erecting load -bearing walls, you can use full -bodied and hollow bricks. Also pay attention to if the facing brick is chosen as a cladding, then be prepared for the construction of the main wall and the cladding is carried out simultaneously. Thus, the facade of the building is formed, creating the necessary element of building structures.
At the stage of designing the building, whether it is a high -rise house or cottage, calculations for strength and thermal conductivity and a number of technical characteristics relative to brick walls are carried out. As a result, builders can choose a brick that meets all the requirements of technical standards.
As for the price of bricks, construction brick has different price categories. And this is mostly dependent on the shape and size. And the quality of Russian manufacturers is almost far behind the imported ones, which can cost you much cheaper.
As already said, there is a full -bodied and hollow brick. Each species has its own advantages and purpose. Full -bodied bricks are able to withstand heavy loads. Hollow bricks respectively for less load, and have lighter weight and high thermal conductivity. Voids prevent the passage of heat, that is, the walls erected from hollow bricks will practically not let the heat out. In addition, the price of hollow bricks is more profitable.
How to choose a brick
Before buying a brick, find out for yourself — what you are building from brick. Walls, base, partition or facade cladding. After the solutions, pay attention to the following parameters:
1. Construction or facing brick. Construction brick is designed for the main part of the structure, and it can have chips, cracks, uneven coloring, interspersing of lime or other foreign materials. And the facing brick is smooth, without chips, interspersed, cracks, with uniform coloring, serves to give the aesthetic appearance to the building;
2. Hollow (also called slit) or full -bodied brick. Hollow brick like a thermos retains heat in your house. A full-bodied brick is low to maintaining heat, but due to the lack of emptiness, it is stronger. Here the choice depends again on the purpose of the work. We have already said that hollow bricks for load -bearing walls are more than a suitable option. And the base, partitions or furnaces, with full -bodied bricks will turn out more efficiently;
3. Brick strength. Brick in strength is from M75 to M500. In Russia, a brick M100 — M200 is produced. For the basement and chimney channels, the M200 is considered suitable. And for the wall without load, for sheds, partitions, small buildings, etc. p. A brick M100 is proposed. M 150 is universal and it can be used in buildings up to three floors as a component of the wall;
4. Brick manufacturing method — production technology. There are two methods of manufacture: plastic molding and semi -dry pressing. Plastic molding is a classic method in which each brick is cut from a clay mixture and burned in furnaces. In the method, pressing brick receives a specific form and smoothness. Semi -dry pressed bricks are not suitable for places with high humidity (foundation and t. p.). If you still want to use such a brick, then carefully read the information about the production of this material. Because, in most industries, the problem with moisture resistance has already been solved, and you can safely purchase the material;
5. Dimensions. There are bricks with the same characteristics, but with different sizes. The most popular: single (250x120x65mm), one and a half (250x120x88mm) and double (250x120x138mm) bricks. The larger the size, the more expensive the price, but the construction process is accelerated;
6. The surface of the brick. A smooth brick is used on the front side, the corrugated side is well suited for subsequent finish;
7. Also pay attention to the frost resistance indicators of brick. The technical characteristic indicates F-50 values. Here the letter F means an indicator of frost resistance, and the numbers are the number of frost resistance cycles. For example, a brick with F-50 values you
