dc.description.abstractThe aim of this study is to investigate the chloride ions diffusion in sound and cracked concrete under compressive loads. The model includes the analytical setup and data analyses. The governing equations are modified to account for the no-constant chloride diffusion coefficient. With this condition it is possible to define several terms in the time domain to predict the service life of structures. The material is a saturated and hardened cement paste under non-steady-state conditions. Loads are studied for linear and non-linear material states. The predicted values at the depth of steel reinforcement ranges from 0.1 to 0.3% in 7–20 years. The ratio of the chloride diffusion coefficient under loading and no-loading is 9, whereas the chloride diffusivity coefficient in cracks is 0.9–1.3 times the chloride diffusion coefficient under loading.en
