Abstract
FIELD: manufacture of building materials. SUBSTANCE: expanding cement additive is prepared from aluminium, lime, and gypsum-containing components, namely, wt. -%: bauxite or kaoline clay, 22-46; waste dolomite dust, 4-8; gypsum- containing sludges from neutralization of hydrolysis acid in titanium dioxide production, 30-40; and wastes from acetylene production or dust caught in limestone calcination process, 20-30. EFFECT: reduced power consumption and raw material cost.
