Influence of CuO on the Mineral Formation of High Cementing Clinker

摘要

The influence of CuO on the mineral formation of high cementing clinker is reported in this paper. Content of C_4A_3S and C_3S in clinker burned at different temperature was determined by XRD. The phasic composition of clinker was examined by XRD. The crystal structure of C_3S and C_4A_3S were analyzed by TEM and IR respectively. The results show that 1.0% CuO added to raw material can lower the clinkering temperature, improve the burn-ability, and promote the formation of C_3S and C_4A_3S minerals.CuO can also distorted the crystal structure of C_3S and C_4A_3S .
