摘要：

Chloride ingress in concrete structures has been defined and modeled using Fick's law of diffusion by many researchers, and most of the researchers considered diffusion coefficient and surface chloride content as constants. Now, it has been recognized that diffusion coefficient (D) and surface chloride content (Cs) varies with the increase in age of the structure. This paper presents a methodology for evaluating the values of D and Cs for concrete structures of different age groups, and also investigated the variation of these parameters with respect to age of structure by using results of a field survey.
