Abstract: Due to the presence of multiple aggressive ions, seawater is a complex natural environment to understand for the durability of cement based materials. Experimental studies and observations have given numerous advances in the conception of materials resistant to seawater, but the modeling of degradation phenomena is globally weak. Thus, a new modelling approach, CITRAR, consisting in the coupling of reactive and transport laws at the microstructure scale, is applied to understand the chemical degradations occurring in cement based materials due to seawater
