PROBLEM TO BE SOLVED: To provide a cement composition which can increase the usage of waste as a whole as compared to the conventional general-purpose cement compositions, enables reduction of energy as a whole as compared to the conventional general-purpose cement compositions, and obtains excellent fluidity as cement property.SOLUTION: Clinker A [clinker having an amount of CAF of 5-12%, a total amount of CA and CAF of <22%, an amount of CS of ≥55% and an iron modulus (I.M.) of 1.3-2.3] close to general-purpose clinker and clinker B [clinker having an amount of CAF of ≥15%, a total amount of CA and CAF of ≥22%, an amount of CS of ≥55% and an iron modulus (I.M.) of ≤1.3] are used together as clinker in a cement composition. By using the clinker B at the same time, a cement composition excellent in fluidity can be obtained and excellent crushability during production is also ensured. |
