Abstract: At present, the stacking of steel slag has caused serious environmental pollution and resource waste, so the utilization of steel slag resources is imminent. Using steel slag powder in cement-based materials can not only improve the utilization rate of solid waste resources, but also reduce the consumption of natural resources and reduce CO2 emission by acting as a substitute for cement. The physical and chemical properties, cementitious properties and active excitation modes of steel slag were introduced. The resource utilization of steel slag powder in concrete composite cementitious materials, solid waste cementitious materials, filling cementitious materials and dry mixed mortar was reviewed. The effect of steel slag powder on the properties of cement-based material was analyzed from the aspects of setting time, workability, mechanical properties, durability and volume stability. Adding proper amount of steel slag powder effectively improves the properties of cement-based materials, especially in regulating the workability of mixes and enhancing the durability. Finally, the existing problems of the application of steel slag powder in cement-based materials and the future research direction were proposed.

Key words: steel slag powder, cement-based material, cementitious activity, workability, durability, mechanical property
