摘 要:為探究高抗蝕硅酸鹽水泥提高混凝土的抗滲性能機理,試驗研究了普通硅酸鹽水泥混凝土及特制高抗蝕硅酸鹽水泥混凝土的抗壓強度、氯離子擴散系數和直流階躍電阻率。結果表明,高抗蝕硅酸鹽水泥不是通過提高混凝土強度而主要是通過降低內部空隙率及減少連通性來實現混凝土抗滲性的提升。
Abstract: In order to explore the mechanism of high corrosion resistance portland cement to improve the impermeability of concrete, the compressive strength, rapid chloride diffusion coefficient and direct current step input resistivity of concrete with ordinary cement and high corrosion resistant cement (HCRC) were studied. The results show that HCRC can improve the impermeability of concrete not by improving the strength of concrete, but mainly by reducing the internal porosity and connectivity.
