QUICK HARDENING MATERIAL, METHOD FOR PRODUCING IT, AND QUICK HARDENING CEMENT COMPOSITION USING IT
To provide a quick hardening material and a quick hardening cement composition excellent in development of early strength, without impairing development of long-term strength and the appearance of cement concrete. A cement quick hardening material which comprises a calcium aluminate clinker ground product obtained by grinding 100 parts by mass of a calcium aluminate clinker in the presence of from 0.2 to 3.0 parts by mass of a fatty acid represented by the formula (RCOO) n X (wherein R is a saturated or unsaturated hydrocarbon, n is 1 or 2, and X is hydrogen, an alkali metal or an alkaline earth metal), gypsum, a retarder and an alkali metal carbonate.
