摘　　要：从强度和化学结合水含量两个方面,研究了钢渣比表面积对钢渣水泥复合胶凝材料水化性能的影响,并采用灰色关联分析方法探讨了钢渣颗粒粒径分布对钢渣水泥复合胶凝材料水化性能的影响规律,结果表明：16.57 ～31.39 μm范围的钢渣颗粒对其影响最大,并且确定钢渣较佳比表面积为453 m2/kg,同时,增加4.62 ～31.39 μm范围的钢渣颗粒含量,有利于提高钢渣活性,改善复合胶凝材料水化性能.From the two aspects of strength and content of chemically combined water, the influence of specific sur- face area of steel slag on the hydrating capacity of steel slag-cement complex binders is studied and the influence of the particle size distribution of steel slag on the hydrating capacity of steel slag-cement complex binders is investiga- ted with the method of gray correlation analysis. Results show the effect of 16.57 ~ 31.39 μm steel slag panicles on it was the most. Eventually,the optimal specific surface area of steel slag is 453 m2/kg,at the same time,we should try to increase the mass fraction of 4. 62 - 31.39 μm particles, in favor of increasing the activity of steel slag and improving the hydrating capacity of steel slag-cement complex binders.
