| Abstract: | This paper adopts chloride ion permeability of concrete with rapid determination method of chloride ion diffusion coefficient （RCM method）, and analyzes influence on concrete resistance to chloride ion penetration of type and quality of mineral admixture. Result shows that, under the same gelling system, concrete with mineral powder has better properties of resistance permeating of chloride ion than that with ash slag. And when compound admixture ratio is fly ash and mineral according to 1 ： 1, concrete has higher resistance to chloride ion penetration. Under the same condition, the permeability coefficient of fly ash concrete is 2-3 times of mineral powder series. |
