摘 要:为探究高抗蚀硅酸盐水泥提高混凝土的抗渗性能机理,试验研究了普通硅酸盐水泥混凝土及特制高抗蚀硅酸盐水泥混凝土的抗压强度、氯离子扩散系数和直流阶跃电阻率。结果表明,高抗蚀硅酸盐水泥不是通过提高混凝土强度而主要是通过降低内部空隙率及减少连通性来实现混凝土抗渗性的提升。
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.
