Chloride adsorption is very ambiguous in the mechanisms of deterioration of concrete exposed to marine environment. Author suggested that chloride adsorption with cement hydrates depends on pH value of pore solution. However, adsorbed chloride ions can be dissolved in concrete under the combined deterioration environment of carbonation and chloride penetration. In the condition, the most crucial issue is the amount of dissolved chloride ions in cement paste due to carbonation.
In this study, dynamics experiment was designed to quantify the effect of CaCO3 on chloride adsorption. Based on the experiment results, the final goal of this study is to develop integrated system for predicting chloride adsorption /desorption behaviors.
