摘　　要：对比研究了多种助磨剂对钢矿粉比表面积、活性指数的影响,在此基础上,选出3组性能较好的助磨剂三乙醇胺、三异丙醇胺和多聚磷酸钠进行正交试验,确定了钢矿渣体系复合助磨剂的最佳掺量为:三乙醇胺0.03%,三异丙醇胺0.15%,多聚磷酸钠0.05%,其28 d活性指数提高了15%。Both the grinding effect and the activity of steel slag and bhtst furnace slag with multiple grinding aids were investigated. Based on that result,the orthogonal test was designed to three kinds of selected grinding aids, which are triethanolamine, triisopropano- lamine and sodium polyphosphate. The best mix proportion was that 0.03%triethanolamine ,0.15% triisopropanolamine and 0.05 % sodium polyphosphate.The result also indieat that activity of steel slag and blast furnace slag with the best mix proportion is increased by 15%.
