摘要：
Industrial waste-like slag has caused serious problems all over the world. In this paper, blast furnace slag was ground to be superfine powder and partial replacement of cement. Multiple contents of slag powder used in cement were studied by cement paste, cement mortar and cement concrete experiment. Water requirement of normal consistency, setting time, soundness, fluidity, compressive and flexural strength were chosen to evaluate the performance of cement-based with different contents of slag powder. The results show that superfine blast furnace slag powder can be effectively used in cement with high contents. The strength of cement mortar with 70% superfine blast furnace slag powder still can meet the requirements of Portland cement P center dot O 32.5. Meanwhile, superfine blast furnace slag powder can improve fluidity of cement-based materials.
