摘　　要：研究了矿渣的粉磨细度、激发剂的掺量、改性剂的种类与掺量对矿渣胶凝材料的干燥收缩性能及强度的影响。掺加9 %～10 %的自制激发剂和10%左右的硅酸盐水泥 ,并控制矿渣的粉磨细度 ,可以使矿渣胶凝材料的干燥收缩率降低到与硅酸盐水泥相近的程度 ,且强度相应提高 ,达到对矿渣胶凝材料综合改性的目的。The slag grinding fineness,additives of exciting agent,modifier kind and quantity,which influence the dry contractibility and strength of slag cementing material,have been studied.The dry contraction percentage of slag cementing material may lower close to portland cement degree by means of adding 9%～10% of exciting agent made by ourselves and about 10% of portland cement as well as control slag grinding fineness during research .The strength is relatively increased up to the comprehensive modifing purpose for the slag cementing material.
