A New Approach for Critical Chloride Content in (Non)Carbonated Concrete

Abstract:

Article Preview

The purpose of this study is to establish an analytical formulation for determination of the critical chloride content in concrete. In this study, factors affecting the critical chloride content such as mix proportion, environment, chemical evolution of pore solution with time, carbonation and so on are taken into account. The numerical simulation program of cementitious materials, HYMOSTRUC was utilized for the construction of the formulation. This was expressed as a free chloride content in a mass unit of concrete as a time function.
