硅酸盐水泥复合胶凝材料浆体的流变性研究

Experimental Study on Rheology ofCompound Cementitious MaterialsPaste with Portland Cement

利用硅酸盐水泥、磨细矿渣和硅灰配制了不同的胶凝材料系统。使用专用浆体流变仪研究了材料系统浆体的流变学类型和触变性以及水固比、矿渣细度、矿渣掺量和减水剂对浆体流变学特性的影响。

Different systems of cementitious materials were prepared with Portland cement,grinding ground blastfurnace slag(GGBFS)and silica fume.The rheological type and thixotropy of the pastes,the influences of watersolid ratio,fineness and percentage of GGBFS,and water reducer on the rheological characteristics of the pastes were investigated with a special paste rheometer.
