超细矿物粉对C70混凝土性能的改善

Performance improvement of C70 concrete by microfine admixtures

研究了C70混凝土中掺加超细粉煤灰与超细矿渣后其工作性、抗压强度及抗渗性的改善,认为合理掺加超细粉煤灰与超细矿渣取代水泥,C70混凝土的工作性改善效果明显,而强度及抗渗性也明显提高.同时,它们的掺加降低了混凝土中水泥的用量,可作为绿色材料,有研究和工程利用的价值.

This study focuses on the improvement of the workability,compressive strength and penetrability counteraction of C70 concrete blended with microfine FA and microfine Slag. It draws a conclusion that when microfine FA and microfine slag substitute cement in a proper way, the workability, compressive strength and penetrability counteraction of C70 concrete can all improve greatly. At the same time, as their blending can decrease the usage of cement, they are green materials, which is valuable for both laboratory study and project utilization.
