This paper aims to study the effects of the alkali-aggregate reactivity in concrete dams and to estimate the consequences of the remaining potential of further reactivity. A bi-phase damage model apt to described the degradation of concrete affected by the alkali silica reaction is presented and used to simulate the behavior of an existing gravity dam. The different roles played by the temperature and moisture diffusions within the body of the dam are evidenced.
