The current utilization rate of steel slag is only 22% in china, far behind the developed countries. At present, the amount of slag deposited in storage yard adds up to 30Mt, leading to the occupation of farm land and serious pollution to the environment. Improving the slag utilization is an important way to resolve these problems. The physical and chemical characteristics of steel slag were analyzed and then the research progress of steel slag utilization at home and abroad as recycled raw material in steel enterprise interior, aggregate of road and hydraulic construction, cement additive and concrete admixture, materials for waste water or gas treatment, construction materials and fertilizer in agriculture production were introduced respectively. At last, the important routes and critical problems for large-scale utilization of steel slag were proposed.
