Diffusion-Addsorption Model

The COMSOL Multiphysics model of the motion of chloride ions in cement/based materials.

Model of transport of chloride ion through a concrete sample in contact with chloride solution. Fickian diffusion and binding according to Freundlich, Langmuir and linear isotherms is assumed inside the sample. The model is described in detail in:
