Numerical simulation of rapid chloride migration test of concrete

Author

Abstract
A numerical method to predict the migration coefficient of concrete is presented. According to NT BUILD 492, the rapid chloride migration (RCM) test can be described as a process of charge passed through a concrete conductor. The chloride migration coefficient is simulated on the basis of the phenomenological relationships between conductivity and current, current and flux, flux and the migration coefficient. The conductivity of cement paste is defined as the ratio of pore solution conductivity to formation factor. A prediction of the formation factor is outlined from the cement hydration and HYMOSTRUC3D model. Finally, validation and a discussion on the simulated results are presented.
