Chemical substantiation of corrosion
All building materials in contact with the external environment feel its negative effects. A complex of physical and chemical factors, such as daily temperature changes, carbon dioxide, which is always present in the atmosphere, the effect of precipitation representing a mixture of water and a number of salts inevitably provoke corrosion. Concrete is also subject to corrosion, its protection is the key to reliability of the entire structure.
The capillary porous basis of concrete made using classical technology, by mixing sand, gravel, cement and water, is greatly affected by adverse factors, although hydrophilizers are used in the production of concrete. Under the influence of adverse factors in the porous formation, crystals arise, their growth causes the formation of cracks. Salts of sulfuric, salt, coal and other acids, which are in a significant concentration in the atmosphere, also show a destructive effect on construction devices.
