摘　　要：　利用磨细粉煤灰、磨细矿渣和硅灰作为矿物掺合料,分别研究了矿物掺合料、高效减水剂以及它们复合作用时对水泥净浆浆体流变性能的影响情况。研究结果表明:矿物掺合料与高效减水剂"双掺"时,大大提高了水泥浆体的流动性。在此基础上,本文着重分析了高效减水剂与矿物掺合料对水泥基材料流变性能的作用机理。This paper studys the influence of the mineral admixtures such as ultra-fine fly ash,ultra-fine slag and silica fume,superplasticizer,as well as their composite effect on the rheological performance of cement paste.And the result shows the fluidity of cement paste is greatly improved when both mineral admixtures and super plasticizer are added.Based on experiments,it is analyzed that the effect of mineral admixtures and superplasticizer on the rheological performance of cement based materials.
