Abstract
The durability and service life of reinforced concrete structures in the marine environment have been the subject of several studies in the literature, due to the great importance for port infrastructure and the high level of aggressiveness offered by this environment to reinforced concrete structures, mainly by the chloride ions action in the corrosion of the reinforcement. In this way, the present chapter deals with the modeling of chlorides concentration profiles, where an analysis recently developed for application of the Modified Holliday Equation is presented. For this, different profiles models were performed, representing different materials and environmental conditions using this new methodology. The results showed that the model based on the Modified Holliday Equation can represent the diffusion zone for structures with different characteristics (materials, environmental, age and location), and is also able to represent chloride concentrations in the convection zone, allowing to estimate the service life of structures built in marine environments around the world.
