摘　　要：结合作者研制的适用于硫铝酸盐水泥混凝土的新型缓凝减水剂,研究了在硫铝酸盐水泥中复合矿渣、粉煤灰对混凝土性能的影响,制备出了强度高、坍落度大、坍落度损失小、膨胀适度的泵送硫铝酸盐水泥混凝土,分析了矿物掺合料在水泥水化中的作用机理。Combining addition of a new type of retarder superplastieizer and mineral admixture, fly ash and ground furnace slag, a sulphoaluminate cement concrete has been prepared, which is suitable for pumping and have many good properties such as high strength, large slump, small slump loss, and appropriate expansive rate. The mechanism of mineral admixtures in the hydration of sulphoaluminate cement was also discussed.
