What is the density of the brick?
Brick is one of the most famous building materialsmaterials. He has a number of important properties that make him irreplaceable. The brick is resistant to the effects of precipitation, is able to withstand a large number of cycles of freezing, etc. One of the most important characteristics of this building material is density. It determines its qualities such as thermal conductivity, mass and strength.
Ceramic brick
Well-known to all the material of red color,Although modern technology has allowed to expand the number of shades. The density of ceramic bricks has a wide spread, since it is produced for various purposes. This brick is made of clay, which is fired in special furnaces. It is divided into solid and hollow. In the first case, the density of ceramic bricks reaches 2000 kg / m3. This indicates its low porosity and high strength. Therefore, solid bricks are used for the erection of load-bearing walls and structures, columns, etc.
Hollow brick is not so tight. This indicator varies between 1100-1400 kg / m3. It is undesirable to use for constructionbearing structures. Hollow brick is used to build light walls and to fill the frame. Due to its voidness it has excellent heat and sound insulation qualities.
Lime brick
Produced from a mixture of lime with sand. This material is cheap, can be painted in a variety of colors, but it turns out to be fragile (in comparison with ceramic), heavy and easily passes cold and heat. Because of these qualities, the use of bricks is limited to the erection of internal partitions. The use of this material to create load-bearing walls is unacceptable. Also, do not use it to build stoves, because when it is heated it deforms.
The density of bricks of silicate full body is 1800-1950 kg / m3, and with voids - 1100-1600 kg / m3.
Clinker brick
Produced from dry clay, which is firedat elevated temperatures. As a result, the products are very durable, wear-resistant. This material is not afraid of dampness and difficult operating conditions. Therefore, it is used in places with high load: with the power of roads, erecting basement floors. Well, he shows himself and when facing the houses.
The density of full-bodied clinker brick reaches 1900-2100 kg / m3, strength - M1000. The porosity does not exceed 5%, due to which the material is slightly exposed to dampness. Products are designed for 100 cycles of freezing-thawing. However, the production of such a brick is much more expensive than ceramic. Due to its high density, the material is heavy and has a high level of thermal conductivity.
Fireclay bricks
This building material is designed for veryhigh temperatures, it withstands heat up to +1600 degrees. Therefore fireclay bricks can be called not just fireproof, but fireproof. It is indispensable for laying ovens, fireplaces and other structures that will be exposed to high temperatures. Since the material is often used to decorate the decorating elements of the interior, it is produced not only standard rectangular shape, but also arched, trapezoidal and wedge shaped. The density of bricks varies from 1700 to 1900 kg / cm3.
However, the products we are consideringclassify not only by the material of manufacture, but also by purpose. Therefore, many characteristics will be determined by the sphere of application. Including the choice of raw materials will depend on this.
Facing bricks
Used for masonry from the outside of buildings. High demands are made on its appearance. The brick must be smooth, smooth and glossy. It is hollow, due to which it performs 2 functions. The outer layer of the brick is both decorative and warming. For external cladding material of various shades is used. Varieties of colors are achieved through the use of various technologies of firing, temperature regimes and composition of clay masses.
The density of facing bricks ranges from 1300 to 1450 kg / cm3, and porosity can reach 14%. This is enough to ensure a high level of strength, but do not forget about the thermal insulation properties. High requirements are imposed on the frost resistance of the material, since it constantly contacts the external environment.
Ordinary brick
Used for interior work, erectionwalls, etc. Separate high-strength brick, which is used for the construction of load-bearing structures. In the first case, such an indicator as the density of bricks varies from 1100 to 2000 kg / cm3, depending on the scope of application. So, hollow bricks will be used to fill the frame and / or the device of internal partitions, since it will not load the foundation. For external or load-bearing walls, it is best to take a high-strength material. The density of bricks in this case will exceed 2000 kg / cm3.
