N2 - This paper presents a study on the change of workability, strength and durability, including the resistance to freezing and thawing, salt attack and diffusion coefficient of chloride, of high-performance concrete (HPC) in which part of the ordinary portland cement (OPC) was replaced by superfine mineral powder of phosphoric slag (SFPS). The results of this study show that the partial replacement of OPC by SFPS can increase the fluidity, improve the compressive strength, decrease the chloride diffusion coefficient of concrete and obtain good durability of HPC.
