摘要：研究了花岗岩石粉、粉煤灰等矿物掺合料对水工混凝土抗氯离子侵蚀性能的影响，采用RCM法测定了氯离子在混凝土试件内部扩散系数的变化规律，并研究了矿物掺合料的掺量与水工混凝土抗氯离子侵蚀性能的关系。结果表明，矿物掺合料混凝土抗氯离子侵蚀性能较普通混凝土得以提高，通过混凝土双掺与单掺矿物掺合料的抗氯离子侵蚀性能的比较，双掺时抗氯离子侵蚀性能比单掺花岗岩石粉时更好。 Abstract: The effect of granitic powder, fly ash and other waste mineral admixtures on chloride resisting properties of hydraulic concrete are studied, and the change rule of internal diffusion coefficient of chloride ion in concrete specimens is tested by the method of RCM, furthermore, the relationship between the content of waste mineral admixtures and chloride resisting properties of hydraulic concrete performance is studied. The results show that chloride resisting properties of the concrete with admixtures is better than that of ordinary concrete, and the performance of concrete double mixed with admixtures is better than that of concrete single mixed with admixture.
