The Clinker Minerals Effect on the Cement Hardening Kinetic Constants

Abstract:

The work is devoted to the study of the relationship between the individual clinker minerals content, the stone compressive strength in different periods of hardening and the binders kinetic hardening constants. It is shown that C₃S and C₂S affect the cements’ kinetic hardening constants in the early and long-term periods in different ways. There is a positive effect of C₂S on the ultimate compressive strength and a sharp decrease in the dependence of the stone ultimate strength on C₃S in the later periods. The initial hardening rate in high-cement cement is established to increase sharply with an increase in the C₃A content from 5 to 12%. The increase in the C₃A content up to 12% in low-cement cement has little effect on the initial hardening rate value.
