Abstract

Steel corrosion is one of major problems that affect the durability of reinforced concrete structures. Chloride concentration is the key parameter for the steel corrosion risk of reinforced concrete exposed to seawater. Therefore, the durability of reinforced concrete can be evaluated by the prediction of chloride concentration into the reinforced concrete. Numerous numerical models have been developed to predict the chloride concentration in concrete however these numerical models have not yet fully simulated the nature of the chemo-physical processes taking place between the concrete and seawater. In this study, the prediction of chloride concentration is carried out by using the geochemical model including chemo-physical process. The geochemical model can improve the accuracy of the durability prediction of reinforced concrete. The accuracy of durability prediction is proved by the comparisons between modelled results and experiments results found in the literature.
