Prediction of a Chloride Ion Penetration Profile for a Concrete

Prediction is based on a one-dimensional finite difference solution of Fick's second law of diffusion, with a variable external chloride concentration and a two-layer representation of the concrete. Surface treatment option has been added in 2006 and mill and fill option added in 2007 in collaboration with Prof. Guthrie of Brigham Young University. Ability to input a measured chloride profile added in 2017.
