Determination of Chloride Ion Penetration Depth of Blended Mortar Using Electrochemical Impedance Spectroscopy
In this study, the influence of silica fume and fly ash on the chloride ion penetration of prestressed concrete cylinder pipe (PCCP) mortar coatings immersed in a 9.5% NaCl solution was evaluated using the electrochemical data obtained from the electrochemical impedance spectroscopy (EIS) approach. The novel equivalent circuit model (i.e. Dong’s EC model) that considers the ions diffusion and the charge transfer in the cement paste was used to predict the chloride ion migration of the blended mortars. The results indicate that the EIS fitting parameter \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${R}_{ct1}$$\end{document} can be used to predict the chloride ion migration depth of mortar blended with silica fume and fly ash in an acceptable manner under chloride penetration conditions. This study contributes towards the development of chloride resisting PCCP mortar coating.
