Deterioration of Reinforced Concrete Structures due to Chemical–Physical Phenomena: Model-Based Simulation

The deterioration process of reinforced concrete structures due to chemical-physical phenomena can be profitably analyzed by means of model-based simulations, performed by using a mathematical/numerical approach. In this work both the model of humidity, pollutant and temperature diffusion, and the mechanical damage approach have been applied to some real cases with the aim of establishing a possible develop-line for the analysis of degradation that can be applied to real engineering structures. The intend is the evaluation of the structural safety and the prediction of the expected service life of reinforced concrete structures.
