Numerical Study of the Effect of Maturation and Extended Chloride Deposition on Chloride Ingress

Abstract

This study presents the implementation of advanced analytical models designed to account for delayed exposure to chlorides in reinforced concrete structures. These models incorporate the effects of aging, which are known to reduce the rate of chloride ingress over time. The analytical models aim to provide faster predictions of the durability and service life of concrete structures subjected to chloride penetration comparing to finite element based models. To validate the accuracy and reliability of these models, preliminary results have been obtained and compared with those from a reference finite element-based model. The comparative analysis highlights the strengths and limitations of the analytical models, offering insights into their potential application in real-world scenarios. This research contributes to the field of structural engineering by enhancing predictive capabilities for infrastructure exposed to chloride-induced corrosion.
