To prepare highly durable cement concrete for marine infrastructure, the effect of silicon powder (SF), fly ash (FA) and mineral powder (SL) on sulfate corrosion resistance of the high iron and low calcium portland cement (HIPC) were studied. In this paper, a series of experiments were carried out using HIPC cements as the raw material and 20 °C, 5% Na 2 SO 4 solution as the conservation environment. The effect on the sulfate resistance of the system is determined by analysing the mechanical properties of the sample and measuring the corrosion resistance coefficient K to characterize the system’s resistance to corrosion. The results show that the anti-erosion coefficient of HIPC systems with different mineral admixtures has been enhanced to varying degrees, among which the optimal amount of SF is 3%; the optimal amount of SL is 40%; the optimal amount of FA 20%.
