摘　　要：钢渣中掺加粉煤灰高温重构,用正交试验法设计实验方案,考察了掺加量、试验温度及冷却方式对胶凝材料强度的影响。结果表明,掺加粉煤灰可以稳定钢渣品质;f-CaO吸收完全;没有方镁石析出;钢渣的28d活性指数达84%。试验最佳参数为:粉煤灰掺量15%;温度1300℃;热闷处理。The mineral composition and structure of steel slag are modified by incorporating fly ash it at high temperature.The effect of modified steel slag on the cementitious property was investigated by orthogonal test,in which the content of fly ash,calcinated temperature and cooling method were studied.The results show that（1）composition of steel slag is stable;（2）f-CaO are Absorbed;and（3）the activity index at 28 d of modified steel slag is 84%.The optimal test parameter are dosage of fly ash 15wt%;temperature of 1300 ℃ and pyrolytic treatment.
