(TU Delft Materials and Environment) Ye, G. (TU Delft Materials and Environment) Date 2019-01-01 Abstract An analytical model for predicting the relative chloride diffusion coefficient in cementitious materials at different degrees of water saturation is presented in this paper. The model is developed based on the Nernst-Einstein equation and conductivity of cementitious electrolyte, as well as on moisture distribution in the pore structure. Good agreement is found between the model and the experimental data. With the help of the model, the chloride diffusion coefficient of cementitious material at unsaturated state can be determined according to the chloride diffusion coefficient at saturated state, the degree of water saturation and the average pore diameter of the material. A detailed discussion about the inputs and outputs of the model is given in order to facilitate its application for engineering practice.
