摘   要：应用A型复合掺合料（磨细钢渣粉：粉煤灰：硅灰=3:5:2）、B型复合掺合料（磨细钢渣粉：矿渣微粉：粉煤灰=1:2:1）配制复合型掺合料的高性能混凝土，通过电通量试验分析混凝土的抗氯离子渗透性能。结果表明，随着矿物掺合料掺量的增加，混凝土的抗氯离子渗透性能也随之明显提高；复掺A型掺合料混凝土的56d电通量均低于1000C，且当掺量小于30%时，其抗氯离子渗透性能显著优于复掺B型掺合料的混凝土；当掺量大于30%时，复掺B型掺合料混凝土的电通量降低速率高于复掺A型掺合料的混凝土。

Abstract: A study on the anti-chloride ion penetration performance of high-performance concrete is made through the electric flux test, and the high-performance concrete is made with A compound admixtures (steel slag: fly ash: silica fume=3:5:2) and B compound admixtures(steel slag: ground granulated blast furnace slag: fly ash=1:2:1). The results show that the anti-chloride ion penetration performance can be obviously improved with the increase of compound admixture amount; the anti-chloride ion penetration performance of concrete with A compound admixture is significantly better than the concrete with B compound admixture when the admixture amount is less than 30%, and the electric flux of concrete with A compound admixture is below 1000C when the concrete has been cured 56 days; the electric flux decreasing speed of concrete with B compound admixture is higher than the concrete with A compound admixture when the admixture amount is more than 30%.
