HIGH BELITE-BASED CLINKER COMPOSITION EXCELLENT IN INITIAL STRENGTH DEVELOPMENT, METHOD FOR PRODUCING THE SAME, AND HIGH BELITE-BASED CEMENT COMPOSITION

摘要

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% C₂S, and enhancing long-term strength by heightening hydration activity of C₂S; 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% C₂S, the M1 phase in C₃S is ≥12 mass%, and the mass ratio (M1/C3S) of the M1 phase to the C₃S 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.;COPYRIGHT: (C)2013,JPO&INPIT
