| Abstract: | The theoretical model of nitrite ion diffusion in concrete presented based on the diffusion equation of Fick's second law when nitrites were coated to the concrete surface for protection of steel in concrete and the model was evaluated with laboratory data. Finally, the duration of the protective effect of nitrites had predicted based on the present model. |
