PLASTER MINERAL MIXTURE FOR FINISHING BUILDING FACES Russian patent published in 2012 - IPC C04B41/65 C04B28/04 C04B111/20 C04B111/27 C04B111/76 B28B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to construction. The technical result is improved adhesion and cohesion properties, frost- and water-resistance, maintaining the possibility of colour toning of the plaster mineral mixture, recycling nanowastes of asphalt-concrete plants and thermal power plants by using carbonate-silica dust (particle size of 60-90 nm), containing the following, wt %: calcium carbonate CaCO₃ 55-60; silicon oxide SiO₂ 10-13, magnesium carbonate MgCO₃ 22-25, and carbonate slurry (particle size of 20-60 nm), containing the following, wt %: CaCO₃ 95; Fe₂O₃ 3; CaSO₄*2H₂O 2. The plaster mineral mixture for finishing building faces contains the following, wt %: grey portland cement M 400 28-37; carbonate-silica dust 10-15; carbonate slurry 10-15; quartz sand 38-47.

EFFECT: improved adhesion and cohesion properties, frost- and water-resistance, maintaining the possibility of colour toning of the plaster mineral mixture, recycling nanowastes of asphalt-concrete plants and thermal power plants by using carbonate-silica dust.
