中文摘要：

以混凝土的力学性能和抗氯离子渗透性能为主要研究对象，通过正交试验确定了混凝土最优配合比，采用电通量法研究了RHA对混凝土氯离子渗透性能的影响，结果表明，掺RHA后混凝土抗氯离子渗透性能得到改善，利用电镜扫描（SEM）对混凝土试样进行微观分析，探讨了稻壳灰对混凝土强度和抗氯离子渗透性能影响的机理分析。

英文摘要：

It takes the mechanism and chloride ion penetration of concrete as main research subject.It has designed an orthogonal test scheme to make sure the most optimum mixing ratio scheme of concrete.The chloride ion penetration of concrete was studied using the electric flux method.The results show that the chloride ion penetration of concrete is improved when the rice husk ash is added in concrete. It discussed the mechanism analysis of the concrete with rice husk ash of the mechanism and chloride ion penetration, using scanning electron microscopy （SEM）.
