Abstract

The resistance of a coherent granular material, such as mortar or concrete, to crack propagation cannot be appreciated without taking into account the heterogeneity of the material. Heterogeneity results from the presence of aggregates and from the local modifications of the composition and of the behavior introduced by these aggregates in the volumes of intergranular paste situated close to their interface, the “aureoles de transition.” It is possible to modify the characteristics of these zones to develop the global response of the material.
