| Abstract: | According to the no-fines concrete structure characteristics and present research, four different gradation types are selected. Based on mixture ratio design of no-fine concrete, it determines the effective porosity, compressive strength, permeability coefficient of different gradation types, and discusses the influnential factors of effective porosity on compressive strength and permeability coefficient. |
