摘要: 实验测量了混凝土中的钢筋在不同的氯化物含量和不同浸泡条件下的交流阻抗。由于实验数据无法与常见等效电路的阻抗轨迹拟合,可采用阻抗模值而不必求出电荷传递电阻来表征钢筋的腐蚀程度,该方法简捷,得到了与失重法一致的结果。

Abstract：Corrosion of steel in concrete is one of the important research:toplcs. Based on the corrosion process, a couple of electrochemical techniques have been tried to measure the corrosion of rebar. This paper reports some preliminary results on it using AC impedance technique. Because the experimental data could not fit the impedance plot of simple equivalent circuit, the authors determined the corrosion of specimens in terms of impedance modulus
