AB  - This work focuses on a multi-phase chemo-elastic damage model
for the description of the mechanical degradation of concrete induced by the Alkali Silica Reaction (ASR). A threephase and a two-phase simplified versions are
considered. The model accounts for ASR kinetics, depending on temperature and
humidity conditions, and the swelling pressure exerted by the ASR reaction products on the skeleton. Damage and viscous phenomena are taken into account. The
model is used to simulate the experimental tests on concrete reactive beams performed at varying environmental humidity conditions.
