阿利特-伊利米特熟料是通过在水泥熟料中引入非硅酸盐矿物硫铝酸钙而制备的高胶凝性熟料。报道了在1300° C下制备的富硅酸三钙硫铝酸盐的矿物组成和力学性能。研究了铜渣和磷渣对水泥的物相组成、放热性能和抗压强度的影响。用X射线粉末衍射分析了相组成。结果表明，铜渣和磷渣能降低熟料的烧成温度，促进C3 S和C4 A3 S ′的共存。在1300° C下生产的熟料质量令人满意。砂浆28 d抗压强度高于P· II 52.5。
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 C 3 S and C 4 A 3 S¯. 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.
