混凝土不同层次结构抗氯盐侵蚀性能与相互关系的研究

Study of the resistance to chloride penetration of concrete structure on different levels and mutual relationships

针对混凝土多层次结构(水泥浆、砂浆和混凝土三个层次结构)的特点,试验研究了混凝土不同层次结构的抗氯盐侵蚀性能及相互关系。研究结果表明:混凝土中三个层次的抗氯盐侵蚀性能按净浆、砂浆和混凝土的次序增强,高性能混凝土配合比设计应控制三个层次比例,控制浆骨比、砂胶比和砂率等配合比参数,保证混凝土具有较高的抗氯盐侵蚀性能。

The resistance to chloride penetration of concrete structure on different levels and mutual relationships were studied on basis of more levels of concrete （paste, mortar, concrete ）.Experimental results show that the resistance to chloride penetration of concrete structure on three levels gradually increases in sequence of paste, mortar, concrete, proportion of on three levels and paste aggregate ratio, sand binder ratio, sand ratio of concrete mix ratio parameter must be controlled to have high performance of resistance to chloride penetration.
