A STUDY ON PROPERTIES OF HIGH BELITE CEMENT

Properties of high belite cement (HBC) were investigated, based on the requirements of high performance concrete (HPC), i.e., workability, strength and durability. The research results reveal that high belite cement has the advantages as follows in comparison with traditional portland cement (PC).(1) It reguires less water demand for normal consistency, and posses higher mortar flowability, more compatible with concrete admixture, and therefore offers better workability to concrete.(2) Its strength increases more rapidly in later curing period in spite of its much lower early strength. The strength of HBC at the age of 91d and 180d is over 10 MPa and 15 MPa respectively, higher than those of PC at the corresponding age.(3) At higher curing temperature, the 28d strength of HBC increases with the curing temperature, on the other hands, that of PC decreases. Excellent strength property of HBC at higher temperature is therefore confirmed.(4) It has lower hydration heat evolution and adiabatic temperatu
