Prediction of Chloride Distribution for Offshore Concrete Based on Statistical Analysis.

Chloride-induced corrosion is the main threat to the service life of concrete structures. In order to better investigate chloride distribution in offshore concrete, this study proposed a new prediction model based on statistical analysis as well as a large body of experimental results collected from various sources. A detailed discussion found that the key influential parameters, such as diffusion coefficient ( D ), surface chloride concentration ( C S ) and penetration depth ( x ) are all highly time-dependent.
