چکیده انگلیسی
In this research, the chloride penetration in concrete is modeled under marine environment loadings. Moisture migration model is enhanced to simulate the sorption flux under submerged wetting after long exposure to drying. The non-ideal viscosity of flow in the porous media is modified according to the nature of micro-pore structure by modeling the sensitivity of different porous networks (dense and coarse) to react towards the external environment. The strong sorption flux generated as a result of wetting and drying cyclic exposure is modeled by applying hydraulic pressure at the exposed surface. Chloride profiles are then simulated by coupling the enhanced moisture conductivity model with chloride transport model.
