摘要
实验证明:由于在碱性介质中钢筋表面存在钝化膜,使钢筋锈蚀过程的介电谱具有明显特征,因而从其Cole cole图可以得到钝化膜的电容特性.
The characteristics of dielectric spectrum of rebar corrosion in mortar was studied. Due to presence of passivation film on the surface of rebar, a special shape of curve appears in the Cole-cole plots from which the capacitance of film can be estimated.
