Research on Sulfate Solution Diffusion in Concrete
Abstract：Study on the diffusion behavior and characteristics of sulfate in concrete is very important to prevent and reduce damage to the concrete caused by sulfate corrosion. According to Fick Law, Sulfate ion diffusion equation in concrete, considering the chemical function, was established. Based on the theoretical analysis above, the corresponding process was simulated by Fortran language programming. The results show that the sulfate ion concentration in concrete increases with the increase of water-binder ratio and corrosion solution concentration, that it decreases with the increase of maintenance time; that it deereses with the increase of stress ratio when stress ratio is below 0.5, while increases with the increase of stress ratio when stress ratio is above 0.5.
