CLINKER COMPOSITION, AND CEMENT COMPOSITION
PROBLEM TO BE SOLVED: To provide a clinker composition which allows hydration activity of high belite-based clinker to be improved so that excellent strength developability can be obtained while keeping excellent flow properties of cement, and to provide a cement composition obtained by using the clinker composition.SOLUTION: The clinker composition contains: 50-70 mass% of 2CaO-SiO, 11-14 mass% of the total of 3CaO-AlOand 4CaO-AlO-FeO, 0.33-1.09 mass% of SOsolid-solved in a solid phase, 0.55-1.10 mass% of MgO, 0.09-0.26 mass% of PO, and an Sn-containing component of 40-250 ppm in terms of Sn, and is characterized in that the lattice volume of β-2CaO-SiOin the 2CaO-SiOis 347.2Åor larger. The cement composition contains the clinker composition and gypsum.SELECTED DRAWING: None
