This paper mainly studies the substitution effect of the superfine powder on cement after the use of superfine powder in concrete. The experiment shows that the superfine phosphor slag powder can significantly improve the performance of C60 high-performance concrete and has an important role in the retention value of 1h slump. The incorporation of superfine phosphorus slag powder can reduce the incorporation of gelled materials and reduce the quantity of the gelation materials by about 50kg when it meets C60 grade concrete strength. Compared with other mineral admixtures, ultrafine phosphorus slag powder can improve the durability of concrete and reduce the early cracking tendency of concrete in C60 high performance concrete. The C60 high performance concrete has the characteristics of good working and easy to crack, and has the technical and economic advantages of similar products in the market.
