A simplified diffusion model is given in the present paper to represent the chloride diffusion in porous concrete. The model with appropriate effective diffusion coefficient is shown to represent equally well as the more complex diffusion/reaction model proposed by Pereira and Hegedus. 4 However the present model has the main advantages of being amenable to an analytic solution and ease of model parameter estimation.
