Effective Diffusion Coefficient of Chloride Ion in Concrete in Marine Environment

The marine exposure tests of concrete specimens were performed in Basuo Port,Hainan,in the worst marine corrosion environment in China.The time dependence of penetration content and effective diffusion coefficient of chloride ions in concrete under splash zone condition were investigated,which may be used to evaluate the durability of concrete materials and to serve as a reference for predicting the service life of concrete structures.
