【Abstract】 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.更多还原
