CELLULAR CONCRETE MIXTURE AND METHOD FOR PRODUCTION THE SAME Russian patent published in 2005 - IPC

FIELD: building material technology, in particular heat-retention concretes.

SUBSTANCE: cellular concrete mixture contains (mass %) Portland cement 15-30; lime 15-20; aluminum powder 0.03-0.10; silica component (e.g. ground quartz sand) 30-42; alkali inverted slurry, obtained from technological waste from green body cutting, 15-20, gypsum 1.5; and balance: water. Claimed mixture is obtained by preparation and mixing in blender of Portland cement, lime, aluminum powder, ground quartz sand, alkali inverted slurry. In this method slurry is outwashed with water into vessel wherein constant mixing and dispersion are carried out, charged in blender, dosed and mixed with other components in following sequence: ground quartz sand, said alkali inverted slurry, Portland cement, lime, additionally gypsum, aluminum powder. Optionally part of alkali inverted slurry is fed from vessel into slime bath for further agitation and homogenizing.

EFFECT: cellular concrete with improved physical and technical characteristics; stimulation of production process; decreased cost of product.
