摘　　要：本文针对重庆的机制砂与特细砂资源现状 ,用磨细矿渣微粉作掺合料 ,成功配制了初始坍落度 2 0 0mm以上 ,强度等级为C50～C80高性能混凝土 ,并研究了矿渣微粉对机制砂与特细砂复合作细骨科配制的高性能混凝土工作性、强度等性能的影响。In this paper,according to the situation of resources of artificial-sand and super-fine sand in Chongqing,C50～C80 HPC(High Performance Concrete)with original slump up to 200mm,using super-fine slag as additive, was prepared successfully.At the same time,the influence of super-fine slag on properties such as workability and strength of HPC mixed with artificial sand and super-fine sand as fine aggregate was studied.
