Time-fractional derivative model for chloride ions sub-diffusion in reinforced concrete
This article develops a time-fractional derivative diffusion model for the description of the time-dependent chloride ions penetration in reinforced concrete structures exposed to chloride environments. A comparative investigation of time-fractional diffusion model and power law time-dependent coefficient model is studied to demonstrate the validity of this present model. The parameters in the proposed model can be statistically determined by analysing the mean square displacement of experimental data or data fitting techniques, and the model can be used to predict the chloride profiles with time-dependent property. It is also noted that the fractional derivative order in the proposed model characterises the rate of chloride penetration in concrete.
