PROBLEM TO BE SOLVED: To provide a high belite-based clinker composition capable of increasing initial strength of high belite-based clinker and a high belite-based cement composition using the clinker without changing the amount of a mineral composition of high belite-based cement clinker containing 50-70 mass% CS, and enhancing long-term strength by heightening hydration activity of CS; and to provide a method for producing the same, and a high belite-based cement composition.SOLUTION: In a high belite-based clinker composition. which is a high belite-based clinker composition containing 50-70 mass% CS, the M1 phase in CS is ≥12 mass%, and the mass ratio (M1/C3S) of the M1 phase to the CS is ≥45 mass%. Further, when producing the high belite-based clinker composition as much as 1t, chaff ashes are blended as much as 25-250 kg and calcined. |
