摘要
磷渣超细粉（比表面积＞６０００ｃｍ２／ｇ）是一种玻璃质粉体，与矿渣类似，取代砼中部分水泥，可以提高砼的流动性、强度与耐久性。单方砼中磷渣超细粉２７５ｋｇ、５２５＃硅酸盐水泥２７５ｋｇ、水胶比０．２６、高效减水剂９．７ｋｇ，砼坍落度２４ｃｍ，２８天强度１０１ＭＰａ，Ｃｌ－扩散系数比基准砼降低了１／３左右。
Superfine phorsphorus slag with a specific surface greater than 6000cm 2/g is a glassy powder like granulated blastfurnace slag It can improve the flowability,strength and durability of concrete at partial replacement of cement With 275 kg/m 3superfine phorsphorus slag,275kg/m 3 525# portland cement,0 26 waterbinder ratio,and 9 7kg/m 3 superplasticizer,the concrete achieved a slump of 24cm,28d compressive strength 101 MPa,and a diffusion coefficient of Cl - about onethird lower than that of the control portland cement concrete
