CONTRIBUTION TO THE HYDRATION OF EXPANSIVE CEMENT ON THE BASIS OF METAKAOLINITE

THE STUDY OF HYDRATION OF EXPANSIVE CEMENT PREPARED FROM 64% PORTLAND CEMENT CLINKER, 23% METAKAOLINITE AND 13% CASO SUB 4.2H SUB 2O IS DESCRIBED. IT WAS FOUND THAT IN THE COURSE OF A 10-DAY HYDRATION PERIOD, ALL THE GYPSUM ENTERED THE REACTION WITH THE FORMATION OF ETTRINGITE. IN 7-10 DAYS AFTER THE TERMINATION OF THE EXPANSION PROCESSES, TYPICAL STALK-LIKE CRYSTALS WERE TRANSFORMED INTO LEAF-SHAPED OR OTHER FORMATION. ETTRINGITE WAS INDENTIFIED EVEN AFTER 4 MONTHS OF HYDRATION. /HRB/
