Abstract
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 °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 C4A3S¯. The quality of clinker produced at 1300 °C is satisfactory. The compressive strength of mortar curing at 28 d is higher than that of P·II 52.5.
