Abstract
The RCM method was used to test the change and development of chloride ion diffusion coefficient in concrete,and the correlation between the chloride ion erosion resistance of hydraulic concrete and the type and dosage of mineral admixtures was studied.The results show that the chloride ion erosion resistance of concrete with mixed fly ash and granite powder and single fly ash or granite powder is improved,and the improvement is regular.The effect of fly ash and granite powder on the chloride ion erosion resistance of concrete is superimposed,and the chloride ion erosion resistance of concrete is significantly improved under the conditions of 30%and 40%of fly ash and granite powder,indi-cating that the concrete prepared by mixing fly ash and granite powder has good chloride ion erosion resistance and can be used in hydraulic concrete engineering practice.关键词
