AbstractThe main goal of the thesis is to develop a numerical tool modeling the coupled chemo-mechanical processes in the degradation of concrete materials. The present reactive transport model can already predict the internal sulfate attack and the induced fissures from the initial microstructure and simple boundary chemical conditions. The thesis will tackle with the implementation of a new module for complex chemistry able to take into account the main processes of internal sulfate attack but also external sulfate attack and other pathologies of concretes for a wide range of physico-chemical conditions. The numerical tool will be validated on a set of lab experiments devoted to concrete degradation.
