摘要
提出两个不同的阻抗函数,即钢筋阻抗函数和混凝土阻抗函数,从前者可获得钢筋锈蚀速率和钝化膜的信息,从后者可以了解与钢筋锈蚀有关的混凝土结构的信息.从两个阻抗函数导出的10个参数可全面描述与混凝土中钢筋锈蚀及其机理有关的各种信息.
AC impedance function has been used to describe some properties of concrete. Two different AC impedance functions, i. e. the function of rebar Z r(i ω ) and that of concrete Z c(i ω ) have been proposed to study the corrosion rate and the mechanism of corrosion of the rebar. From these functions ten parameters have been derived.
