Diffusion coefficient of chloride in concrete is a predominant factor in chloride penetration into concrete. Two types of diffusion coefficient models are examined here: mean diffusion coefficient D, time-dependent diffusion coefficient D(t). These diffusion coefficients are experimentally derived from the chloride profiles in concrete obtained by the wind tunnel test. It is clearly shown that diffusion coefficients are dependent of water cement ratio but independent of intensity of airborne salt. Time-dependent diffusion coefficients derived based on constant and time-dependent surface chloride are not different. Diffusion coefficient also decreases with increasing of time as explained by other researcher.
