摘要
PROBLEM TO BE SOLVED: To provide a cement admixture having hexavalent chromium reducing ability, capable of producing concrete having small slump loss, effective in effective utilization of desulfurization slag and the like and used in the civil engineering and construction industry and to provide a cement composition and cement concrete using the same. SOLUTION: The cement admixture contains desulfurization slag powder containing =0.5% sulfur existing as non-sulfate sulfur and having =4,000 cm2 /g Blaine's specific surface area. The cement composition contains the cement admixture and cement. The cement concrete is formed by using the cement composition.
