摘　　要：分别以石灰和石膏作为低碱度钢渣的激发剂对低碱度钢渣的蒸压强度进行了研究。结果显示 ,在 1 85℃水热条件下 ,低碱度钢渣制品强度较低 ,氢氧化钙能激发低碱度电炉氧化钢渣活性 ,其激发作用主要是通过激发镁蔷薇辉石和硅酸二钙固溶体来实现的 :掺入少量石膏可大幅提高钢渣的强度 。The activation of steel slag with lower alkalinity by activators(lime and gypsum)in hydrothermal condition was researched. The results showed that the compressive strength of the steel slag is low at 185℃ in hydrothermal condition. Calcium hydroxide can stimulate the activity of electric furnace oxidizing slag with lower alkalinity through activating merwinite and dicalcium silicate. The compressive strength of autoclaved steel slag products can be enhanced obviously by addition of lime or a few of gypsum.
