Abstract
ABSTRACT This study aims to give information, on the one hand, about the evolution of drying shrinkage according to mortar composition, and on the other hand, about the effects of hygro-mechanical microcracking on permeability of cementitious materials. It also deals with the influence of the interstitial fluid nature on the permeability. The results obtained demonstrate that the drying shrinkage of the two studied mortars versus weight loss shows three characteristic phases shown in literature. They also put in light, through the study carried out on the mortar with W/C=0.5, that the permeability of dried samples increases after creep while that in drying creep remains constant, compared to the dried samples without creep.
