摘　　要：测试了在掺高效减水剂的情况下不同矿物组成的阿利特-硫铝酸盐水泥浆体的流动度及流动度经时损失。结果表明:不同矿物组成的阿利特-硫铝酸盐水泥对高效减水剂的适应性有明显差异,C3S含量较高的水泥与减水剂的适应性较好,而熟料中C4A3S含量提高,其水泥与减水剂的适应性变差;在不同矿物组成的阿利特-硫铝酸盐水泥中掺加所选择的三种高效减水剂,其水泥浆体的流动度和流动度经时损失均表现出相同的变化趋势,但作用效果有较明显差异,聚羧酸盐减水剂作用效果最好,氨基磺酸盐减水剂次之,萘磺酸盐减水剂效果较差。The fluidity and fluidity-loss with time of the alite-sulphoaluminate cement of different mineral composition blending with superplasticizer was tested. The results showed that the alite-sulphoaluminate cements with different mineral composition had remarkably difference for adaptability with superplastieizer. If the cement contained more C3S the adaptability would be better, but if the cement contained more C4A3S the adaptability would be worse. For the different superplasticizers, the alite-sulphoaluminate cement with different mineral compositions showed the similar trend to effect the fluidity and fluidity-loss with time. However, the effect was obviously different. The copolymer of polycarboxylate superplasticizer was the best, then amino-sulphonic acid-based superplasticizer, and β-naphthyl sulphonate formaldehyde condensate superplasticizer was the worst.
