METHOD OF PREPARING OF COMPLEX ADDITION FOR CONCRETE MIXTURE Russian patent published in 1995 - IPC

Abstract RU 2033403 C1

FIELD: building industry. SUBSTANCE: method involves passing of ultradispersed active mineral filler on the base of silica with moisture 1.5-30% through the rolls with thickening force 0.01-10.0 MPa following by feeding of thickened material together with chemical addition at their ratio 100: 0.001-100: 20.0 in drum mixer of continuous action. Stirring is carried out at temperature from 0 to +100 C up to preparing of pellets with similar moisture. EFFECT: improved method of preparing. 2 tbl
