In this study, the chloride ion diffusion coefficient of ECC coated with silane-based protecting materials were evaluated. The evaluation was carried out according to NT BUILD 492. The test results show that when the protective material is applied to ECC, the chloride diffusion coefficient is reduced by 40-50%.
