摘要：
Alite-ye'elimite clinker is a high cementing clinker prepared by introducing calcium sulfoaluminate, a non silicate mineral, into the cement clinker. The mineral composition and mechanics of tricalcium silicate-rich sulfur aluminate prepared at 1300 degrees C are reported. The effects of copper slag and phosphorus slag on the phase composition, heat release and compressive strength were investigated. The phase composition was analysed by X-ray powder diffraction. The results show that the copper slag and phosphorus slag can lower the burn temperature of the clinker and promote the coexistence of C3S and C(4)A(3)S. The quality of clinker produced at 1300 degrees C is satisfactory. The compressive strength of mortar curing at 28 d is higher than that of p-II 52.5.
