摘要 基于腐蚀电化学基本原理 ,通过试验得出了混凝土中局部锈蚀钢筋的腐蚀电流“宏微并存”和“边缘效应” According to corrosion electrochemical basic principle,it is concluded that the macrocell corrosion must co exist with microcell corrosion of reinforcements and that the distribution of the macrocell corrosion current is non uniform between active and passive areas of steel reinforcements in a concrete by a series of tests.
