Abstract: The paper focuses on establishanumerical model to simulate drying process of unsaturated concrete exposed to air condition. The model will be set up based on mechanisms of fluid flow. The first part of the paper will present the equations of fluid flow in unsaturated pore milieu and ion ingress into concrete. The numerical model will be performed by Comsol software. The numerical model will be compared with the experimental results from literature, the numerical model offluid flowis validated. The results show that the prediction of numerical model is relatively accurate in drying process of ordinary concrete but with high performance concrete, the accuracy of the model is not really high.
