摘　　要：本论文通过试验研究 ,比较了不同品种、细度的矿物细掺料对新拌水泥基材料工作性的影响 ,考察分析了各矿物细掺料在新拌浆体中的填充、吸水作用 ,以及与高效减水剂共同作用下对浆体流动性的影响规律。In this paper,the effects on workability of fresh cement-based materials by adding the different fineness and different kinds of mineral fine admixture are studied by examination. Then,the functions of filling and drinking water in fresh cement-based materials caused by kinds of mineral fine admixture are analyzed.Finally,the effects on fluidness under the action of mineral fine admixture with superplasticizer are studied.

关 键 词：矿物细掺料 下沉深度 流动时间 高性能混凝土
