Brick - one of the most common materials traditionally used in the construction of buildings and structures. Technology brickwork provides architects and designers unlimited possibilities for the realization creative ideas. Providing reliable protection from external factors, having high fire resistance and relatively low thermal conductivity, brick sets a very high level of safety and comfort as residential and industrial buildings. To appoint a brick building and is divided into front (facing, facade). Building bricks used for indoor or series of masonry for external series, but with subsequent plaster.
Facing brick - a uniform color, has two smooth, flat front surface (the so-called "poke" and "stretcher"). It is used for decorative interior is well known that the brick is "red" and "white" - they differ in composition. Red brick is mostly made of clay and is called "ceramic" white - sand and lime. A mixture of the latter was called 'silicate', and hence the calcium silicate bricks. Sand-lime brick in its form, size and primary use is no different from clay bricks. calcium silicate bricks of high quality must meet the following specifications: First, take into account the compressive strength. For silica brick, he is 15 - 20 MPa. In characteristic brick strength is denoted by the letter 'M' indicating the degree of strength (M100, M125, M150, etc.).
When construction is necessary to consider this option, ie, for the construction of 2 - 3 storey cottage suit brick and brand M100, but in the construction of walls high-rise buildings make better use of the brand M150 and above. Second, the average density of the brick should be 1300 kg / cu.m. Third, the frost resistance of silica brick is 15 cycles and above, for an average strip of Russia is better to choose a brick with frost 35 - 50 cycles. Fourth, the maximum temperature of application should not exceed 550 C. Prices of sand-lime brick depend primarily on its technical characteristics, and hence on the quality. Therefore, buying a brick, always ask the seller license, because the quality bricks will not only provide a good appearance of the building a few years, but his safety, durability. sand-lime brick is good to use with masonry walls and various barriers, but strictly forbidden to use it in laying the foundation, putting stoves, fireplaces, pipes, sockets, etc. A definite plus silica brick in front of a ceramic is its high sound-insulating characteristics, which is an important during construction or interior walls. Techno-economic indicators of sand-lime brick clay brick superior. Its production requires a factor of 2 less fuel is 3 times less energy in 2,5 times less than the complexity of production eventually cost sand-lime brick is 25-35% lower than the clay. Calcium silicate bricks can be solid and hollow. Hollow brick is lighter and due to this reduced pressure on the foundation. In addition, it has lower thermal conductivity, so the walls of a brick can be made thinner without compromising the thermal insulating characteristics. The use of brick with voids provides an opportunity to build in the usual way in improving thermal properties, reduce labor costs, reduce the number of species of silica brick is very broad. If the mixture in the manufacture of silica bricks are added weatherproof, pigments, alkali, then we colored sand-lime brick. It is a brick-lime polnotely stained (the spectrum of colors can even include yellow, black and blue), a brick is generally used as a facing. Produced as a brick silicate porous solid and hollow, hollow bricks / full-bodied with a texture and so cleaved
