Abstract

Theplasticbehaviorofinertandcement-basedmaterialsisanalyzedinthisstudy. Weshow that a Cam-Clay-based model is relevant to describe the consolidation regime of the material during theplasticregime. Forinertmaterials, themodelissuccessfullyusedtoevaluatethecapillarypressure corresponding to the plastic cracking. To assess the cracking risk of the material, the volumetric deformation, the mechanical behavior in the plastic regime and the air entry pressure have to be characterized.
