Ceramic brick

Consider a building material in the article, as a ceramic brick, which is used for masonry work during the construction of structures for various purposes.The emergence of innovative materials does not diminish its popularity.

Scope ceramicbrick

It is used for the construction of load-bearing walls, self-supporting structures.From it build high-rise buildings and low-rise houses.Do not do without this building material in the construction of chimneys, in the regeneration of the basement or room dividers.For these purposes need ordinary ceramic bricks .

Another kind - facing used for the decoration of the external protective layer, which is important to create an aesthetic appearance of the building.

Basic material properties

properties of ceramic bricks are directly connected with the quality of the clay, which is included in its composition, and the precise observance of technology.Optimal raw version - Clay constant composition fines.If at the time of production of the different layers of clay are mixed, prohibited the slightest deviation from the firing technology.If the raw material is melted in accordance with all requirements and is clearly passed by drying program material acquires a predetermined shape and those advantages which are appreciated by consumers so.

Benefits

The advantages of ceramic bricks are as follows:

• small size, which facilitates the process of masonry work;
• excellent strength parameters;
• good heat capacity;
• a high level of sound insulation;
• aesthetics;
• ecology.

Disadvantages Disadvantages in this material too.The brick structure is well hold heat, but heat them for a long time.Reviews of consumers say they need to follow the regular brick house heating and cooling to avoid a frosty period.

Varieties of ceramic bricks

ceramic brick has the following varieties:

• full-bodied;
• hollow or gap (holes may be round, rectangular).

production technology determines the available types of facing ceramic bricks:

• engobed;
• glazed;
• front;
• shaped;
• figured.

Some applications require special varieties.Domestic chimneys, fireplaces constructed of fireclay bricks, which is different fire resistance.Quartz is needed for masonry vaults furnaces, this species has a reflectivity.Carbon charge for the construction of blast furnaces.Clinker used for paving areas, paths.

Dimensions

Usually ceramic bricks have the following dimensions:

• single (250x120x65 mm);
• Bastard (250x120x88 mm);
• double (250x120x138 mm).

According to GOST 530-2007 sizes range as follows:

• single (250h120h65);
• euros (250h85h65);
• thickened (250h120h88);
• single module (288h138h65);
• thickened, having horizontal voids (250h120h88).

Specifications

1. strength - 100 - 300 kg / cm².Specific figures are due to the brand.
2. density ceramic bricks is 1600 - 1900 kg / m³ (full-bodied), 1100 - 1450 kg / m³ (hollow).
3. thermal conductivity figures associated with its kind (hollow or solid brick).Highly effective thermal conductivity is considered to be a hollow ceramic brick 0.36 W / (m · ° C), low efficiency is considered to be full-bodied with an exponent of 0.61 W / (m · ° C).Therefore, from the solid brick buildings are in need of insulation.Dry air within the hollow and slotted products, reduces heat losses.
4. Water absorption - from 6 to 14%.This is a fairly strong performance.However, in the absence of heating, when the wall temperature becomes the same as the outside air temperature, moisture starts to penetrate into the pores.When water accumulates in the pores, it is necessary to be afraid of freezing, because crystallization will lead to increased stress and the appearance of cracks.
5. Water vapor permeability - 0.14 - 0.17 mg / (m * h * Pa).These figures allow the active material used for the construction of residential houses.The walls are made of bricks absorb moisture well, which is a constant companion of man and his life.Such walls can give the accumulated moisture in the surrounding area.Water vapor permeability of the material is better than those of other masonry materials.
6. Shrinkage varies between 0.03 - 0.1 mm / m, this allows us to speak with confidence that a crack in the brick wall unlikely.
7. Fire resistance is very high.Under the influence of such a fire wall can be up to 10 hours.

All technical characteristics of ceramic bricks are regulated by GOST 530-2007.
