摘　　要：矿渣作为水泥混合材已普遍使用,不仅可降低水泥的生产成本,而且能改善水泥的工作性。采用掺加80%以上的矿渣作为主要原料,掺入少量的水泥和其它外加剂,研制具有低水化热和微膨胀的胶凝材料。此矿渣胶凝材料配制方便,具有显著的经济效益及较大的推广价值,尤其是在大型灌浆工程中具有良好的应用前景。Slag,as mixing material of cement,has been widely used.It can not only reduce the produce cost of cement,but also improve the workability of cement.The slag cementing materials of low hydration heat and small expansion is developed which 80% slag as main material has been mixed,as well as small cement and other additives.This kind of slag cementing materials is prepared conveniently and has a remarkable economic benefit and spread value,especially in the massive grouting engineering.

关 键 词：矿渣胶凝材料 水化热 微膨胀
