Assessment on chloride contaminated resistance of concrete with non-steady-state migration method

Abstract

A preparation technology of chloride contaminated resistant concrete was presented. The newly developed non-steady-state migration test method was employed for the evaluation of chloride ions diffusion coefficient of the concrete. The experimental results show that this method has a good correlation with the traditional NT Build 443 method, and it provides an effective and quick approach to assess the resistant capacity of concrete against chloride ions.
