MIXTURE FOR AUTOCLAVE FOAM CONCRETE Russian patent published in 2017 - IPC C04B38/10 

FIELD: construction.

SUBSTANCE: mixture for autoclave foam concrete, including portland cement, quicklime lime, sand in the form of sand slurry with a density of about 1.6 g/l, obtained by wet grinding to a specific surface of particles of 280-300 m²/kg, foam-based protein-based additive, water and waste-condensate, formed during the autoclave processing of the cut foam concrete massif, additionally contains muscovite, co-grinded with sand wet grinding, ferrous sulfate, at the following ratio of components, wt %: Portland cement 17.00-19.38, mentioned muscovite 1.75-1.95, ferrous sulfate 0.52-0.59, mentioned lime 6.9-7.18, mentioned sand 43.42-45.03, mentioned foaming agent 0.23-0.24, water 19.46-19.61, mentioned waste-condensate 8.34-8.40.

EFFECT: increase in the coefficient of vapor permeability and decrease in the coefficient of thermal conductivity of finished products.
