- Many existing prediction models have been developed empirically, based on experimental data. In contrast, the present model was developed based on the theory of electrochemistry for electrolytes in porous materials, which provides a rational framework for developing chloride diffusion models in cementitious materials. As a consequence it is possible to explain phenomena such as why parts of bound chlorides can be released to become free chlorides and why free chlorides in some cases travel paradoxically from regions of low to high concentration. These observations had previously gone unexplained using existing empirical models.
