摘要: This article focuses on the influence of cement matrix porosity triaxial behaviour concrete in presence high confining pressures. It offers new experimental results two concretes, respectively a performance (HPC) and low (LPC). These complement recent studies ordinary (OC), using same large-capacity press. paper serves to better characterise these 3 whose porosities are very different terms volume size; moreover, it emphasises that contribution strength (mainly linked its porosity) decreases at pressures is governed by granular skeleton, even when capillary or entrapped air high. To reach this level residual behaviour, higher needed for HPC, if amount compacted smaller.
