Chloride diffusion study of coral concrete in a marine environment

Using the distribution of free chloride concentration (Cf) and total chloride concentration (Ct) measured by different grades and species of coral concrete (CPC) soaking in sea water, the chloride binding capacity (R), surface free chloride concentration (Cs) and apparent chloride diffusion coefficients (Da) of CPC were calculated. Then, the influence of curing age and exposure time on the durability of chloride in coral concrete were discussed,...
