Abstract

Durability and reliability of concrete structures is influenced by different forms and combinations of attacks such as environmental, mechanical, chemical and/or electrochemical. Among them the damage due to reinforcement corrosion is a rather crucial one and rather often is governed by the presence of chlorides on the surface of the steel. To assess and/or predict this complex effect causing a specific type of concrete damages, both the experimental and modelling methods have to be utilized. As a part of large experimental programme, the evolution of chloride penetration into concrete was measured in different time steps. Based on those experimental results different analytical models were utilized for simulation of the process of chloride ingress and the ability of the models to fit the original experimental data was evaluated.
