Unlike most of rocks, consisting of one mineral, granite contains: 60-65% feldspar - sets granite background - white, gray, pink, yellow, red, green, brown, black, 20-30% quartz - blotches of dark gray to black in color, 10.5% of non-ferrous minerals: black and white mica, hornblende - dark brown crystals or green in color with a distinctive glass shine.

The average density of granite 2700.00 kg / m 3, the approximate weight of 1 m2 of granite products with thickness of 20 mm - 60 kg, 30 mm - 80 kg. Granites are treated abrasive, including diamond tools. Granite products are made with different texture surface treatment: polished, burnished, polished, sawn, heat-treated, buchardirovannoy, "rock."
Granites have low porosity from 1.0 to 3.3%, and low moisture absorption (less than 1%), so hardy and are widely used for exterior cladding works (facades, bases). Granite products for a long time does not collapse under the influence of environmental factors and retain the original appearance. Fine-grained granites are more durable (the first signs of failure occur through at least 650 years) than the coarse-grained (begin to break through at least 220 years).
Lining is made of granite and nakryvnye plate stage. Tensile strength of granite in compression of 90-250 MPa - each cm2 granite steps withstand weight up to 2.5 tons. Only plasticity of inferior marble granite, not less popular rock, a very different origin and composition. Low abrasion allows the use of granite paving in areas of heavy traffic (more than 100 persons per hour) - Sawn granite paving stone production and sale and Granite paving plates of streets and squares are for ages.
In addition to using granite for the exterior cladding of buildings and urban design in recent years there has been a significant expansion of its use for interior decoration, including the manufacture of kitchen worktops.
