Building Materials
The formation of efflorescence is subject to most of the traditional porous building materials (brick, concrete, lime, plaster, etc.), but most strikingly, they appear on the brick facades of buildings. Massive use of brick in construction of houses and cottages gives builders and customers a lot of trouble. Hope that the facade will retain its original color, often disappear with the first rain. After drying the brick is covered by whitish divorce speakers salts. Studies have shown that the efflorescence on the facades are formed by crystallization of soluble salts contained in the cement, concrete, plaster and masonry mortar, brick and ceramic blocks. Education contribute to efflorescence: a high content of soluble solids (salts) in the starting materials (cement, aggregates, mixing water and additives, at least in the brick) high water content in materials and their extra moisture (capillary rising moisture, precipitation), temperature-humidity conditions in which there is a slow and prolonged evaporation of moisture from the material on the surface design; reduced temperature conducive to the formation of hydrates. Salty Efflorescence is called a white salt deposit appearing on the facades.
It is formed due to displacement of water with dissolved salts. In dry weather, salt water rushes out, the water evaporates and the salt crystallizes, adsorbed on the surface of the wall. Just a few days just built a brick cottage in a clean and tidy structure can turn into splodgy whitish stains unsightly construction. But this is not just ugly. Formed in the material structure crystals bursting with pore walls, forming cracks and breaking stuff.
