FORMATION OF HARDENED PRODUCT OF WATER GLASS AND BLAST FURNACE WATER-CRASHED GRANULATED, SLAG, AND HARDENING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To improve controllability of the hardening speed, chemical resistance and strength by mixing alkali hydroxide tow water glass and blast furnace water-crashed granulated slag with each other. SOLUTION: Alkali hydroxide of 3-10 pts.wt. is added to 100 pts.wt. water glass and 30-150 pts.wt. blast furnace water-crashed granulated slags having 3800-8500m2 /g Blaine value, and they are mixed for 1min to 2hr, then are formed to obtain a blast furnace water-crashed granulated slag hardened product.
