Abstract
A cement composition comprising: an ordinary Portland cement clinker in which the contained amounts of C3S and C4AF determined through Bogue calculation are 51-62 mass% and 7-10 mass%, respectively; gypsum; limestone; and assistant containing an alkanolamine, wherein the contained amount of the alkanolamine in the total amount of the ordinary Portland cement clinker, the gypsum, and the assistant is 10-210 mg/kg, the contained amount of the limestone in the total amount of the ordinary Portland cement clinker, the gypsum, the assistant, and the limestone is 3-10 mass%, the cell volume of the C4AF is more than 0.4290 nm3, and the Blaine’s specific surface area of the cement composition is 2800-3500 cm2/g. The cement composition has high strength and excellent fluidity.
