Comportement du béton sous fort confinement

Abstract

This study concerns the identification of concrete behaviour under severe triaxial loadings (rock falls, explosions, ballistic impacts). In order to reproduce high stress levels with well controlled loading paths, static tests are carried out on concrete samples by means of a very high capacity triaxial press (stress levels of the order of the GigaPascal). In addition, it is known for a long time that the water/cement ratio (W/C), entering the concrete composition, is one of the major parameters conditioning the porosity and the strength of ...
