摘　　要：将钢渣粉与矿渣粉以1∶2比例复掺后以30%、50%和80%的掺量用于水泥中,并加入活性激发剂,所配制水泥的各种性能指标满足GB175-2007《通用硅酸盐水泥》的技术要求。分析认为,钢渣粉与矿渣粉复掺提高了颗粒级配的连续性;加入激发剂可以有效促进钢渣的水化,而钢渣的水化又能促进矿渣的水化,提高了钢渣-矿渣复掺粉的活性。钢渣-矿渣复掺粉可以作为混合材大量应用于水泥生产中。The blend of steel slag and GGBS in a ratio of one to two was used as cement admixture. And all the performance of cement could meet the requirements of GB175-2007 〈Common Portland Cement〉 if the content of this mixture were 30%, 50% and 80% respectively. This phenomena could be explained by following reasons： the continuity of the particle size distribution was improved, the rate of hydration of steel slag was accelerated by the addition of activator, and consequently to accelerate the hydration rate of slag, so that the activity of the admixture was increased. Applying this kind of mixture as Portland cement admixture should be recommended.
