Cette thèse a permis d'étudier la perméabilité du béton sous conditions thermiques et hydriques variables, ainsi que l'effet de fissuration. Nombreux essais (mesures de saturation et perméabilité, essai de compressions uniaxiales et triaxiales et hydrostatiques) ont été menés afin d'évaluer l'influence de la température et de la saturation sur le comportement hydraulique du béton sain et microfissuré. En parallèle, un dispositif de mesure de la perméabilité sur béton macro fissuré permet d'étudier le comportement d'une macro-fissure de béton confinée et soumise à écoulement de gaz sec ou l'air très humide à différentes températures. Les essais mécaniques multiaxiaux sont couplés aux mesures de perméabilité sur béton sain et micro-fissuré pa...
