Characteristics and size of silica brick

Silicate white brick is the most popular building material in the Russian market, intended for the erection of walls of buildings for different purposes: residential buildings, institutions, garages, industrial premises and others.

The raw material for its production is lime, quartz sand and additives. The mold is given by dry pressing under pressure and at high temperatures. It is an excellent soundproof material that keeps heat well. It has high strength, frost resistance and durability, and houses from it for a long time retain a good appearance. The main drawback of such building materials experts consider not too high moisture resistance, for example, in comparison with ceramic (red) brick. It is for this reason that it is not suitable for building a foundation, but is used only for building walls. Also do not use it for laying fireplaces, stoves, pipes, suspended structures.

One of the main characteristics of the material is the size of the silicate brick. Today, three types of bricks are used, differing in this parameter. It is a single full-bodied silicate brick, the dimensions of which are in millimeters: length - 250, width - 120, height - 65. It can only be solid, the masonry of it - longitudinal-transverse. Initially, all this construction material had only this size, and products with other dimensions appeared later.

In addition to the single there is another version - one and a half. The size of the silicate brick of this type is equal to: length - 250, width - 120, height 88 (in millimeters). It is full-bodied, porous and perforated. To date, this is the most purchased type of brick.

And the third kind is double. The size of the silicate brick is double : length - 250, width - 120, height - 103 (in millimeters). Double bricks are not solid, but only porous and hollow. It is used for lightweight masonry.

An important characteristic of silicate brick is its strength. They produce products of several brands, for which this quality is determined. The mark is designated with the letter "M", and the number next to it is the level of strength. For example, brick M-125 is able to withstand a load of 125 kg per square centimeter. There is a brick of increased strength - M-150, M-200.

Frost resistance is determined by the value of F, for example: F-25, F-35 and so on. The number next to the letter indicates the amount of frost / thaw the brick can withstand.

In addition, this material is distinguished for its intended purpose. In addition to construction, there is a brick facing and special purpose. The dimensions of the silicate decorative bricks coincide with the dimensions of the building. Finishing must have a perfectly flat surface and edges, as well as the right shape. Facial bricks can be shaped (differ in shape), glazed (colored), textured (with a relief surface).

As for special purpose bricks, this type includes refractory, acid-resistant and other types. The size of the special-purpose silicate brick is standard.
