Abstract：This article designed five series of high-performance concrete specimens, including single fly ash, single mineral powder, single silica fume, double fly ash and mineral powder, double fly ash and silica fume. By conducting experiments on the resistance to chloride ion penetration using the electric flux method at different curing ages, the effects of various mineral admixtures with different dosages on the resistance to chloride ion penetration of high-performance concrete were studied and compared with ordinary concrete. The results showed that the single addition of 16% mineral powder had the best improvement effect on the electrical flux of concrete by comparing the improvement effect of various mineral admixtures with different dosages on the electrical flux of concrete, and its resistance to chloride ion penetration was the best. The high-performance concrete mixed with fly ash and mineral powder had the worst resistance to chloride ion penetration. The variation law of the anti chloride ion permeation diffusion coefficient was consistent with the test results of the electric flux method, indicating that the electric flux method was more convenient and efficient for evaluating the durability of concrete structures.
