Facade Cement Silicate Coating for Ceramic Bricks

Abstract

The facade decorative coating has been developed on the basis of liquid sodium glass and Portland cement modified by the complex ultra- and nano- disperse additive that includes the titanium dioxide, expanded perlite sand and dispersion of multilayer carbon nanotubes. The advantage of the developed coating is the application of Portland cement as silicatizator instead of conventionally applied zinc oxide. The developed cement silicate coating possesses water resistance, good mesh with the base, steam and gas permeability, has the increased durability with the coating lifetime 4-5 times higher than the existing analogs. The presence of multilayer carbon nanotubes within the coating leads to absorption of technogenic electromagnetic radiation. The expanded perlite sand comprised into the silicate coating allows for giving it the textured surface when applied on the base. Application of the developed façade cement silicate coating is possible on the surface of silicate containing materials (brick, cement concrete, cement lime plaster).
