Brick is an ancient and common building material.
This is an artificial material with the correct shape, which has the properties of a stone – strength, water resistance, frost resistance.
There is a red ceramic brick and a white silicate one.
In the production of ceramic bricks, firing of tape or secondary clays up to 1000 ° C, plastic molding or semi-dry pressing is used. The difference lies in the way the clay is prepared.
There are many subspecies of ceramic bricks: hollow (perforated or porous) or solid, embossed and smooth, as well as various types of facing bricks.
Qualities of ceramic bricks: strength and wear resistance;
- excellent sound insulation;
- minimal moisture accumulation;
- ecological cleanliness;
- weather resistance;
- strength from 15 MPa;
- density up to 2000 kg/m3.
The basis of silicate brick is air lime, quartz sand and water. The production technology consists in the action of water vapor at high pressure and a temperature of 170-200 ° C on the molded brick.
Silicate brick has a number of technical characteristics:
- soundproofing; — strength from 15-20 MPa;
- average density from 1300 kg/m3.
- application temperature – not > 550 °C;
- low thermal protection properties (compared to ceramic bricks);
- low frost resistance.
Brick can be of various shapes:
- ordinary 250mmx120mmx65mm;
- one and a half 250mmx120mmx88 mm;
- double 250mmx120mmx140 mm.
And the rarer ones:
- “Euro” 250mmx85mmx65 mm;
- modular single 288mmx138mmx65 mm.
Due to its characteristics, brick is widely used in construction.
