Abstract

This paper presents a finite element model coupling heat, water and salt transport, salt crystallization, deformation and damage in porous materials. The model allows to predict mechan- ical, hygro-thermal and crystallization induced damage. The model performance is illustrated by ` simulating the damage caused by sodium chloride crystallization in Savonnieres limestone, a qausi- brittle porous material. The simulation results suggest that we need to control the nucleation and growth kinetics in porous materials to be able to control salt damage.
