Abstract

The main purpose of this study concerns the characterization of the coupled effect between drying shrinkage and damage for a cementious material. An experimental study on a normalized mortar is then presented in order to characterize the damage effect, induced by drying and desiccation shrinkage on the multiaxial compression behavior. Uniaxial and triaxial compression tests are carried out at different times of drying. The observed increase in uniaxial and deviatoric strengths and decrease of Young’s modulus and Poisson ratio are related to the loss in mass of specimens. These results are commented through the damage processes of material since drying phenomenon causes microcracking.
