Apport d'un nouveau dispositif pour améliorer l'estimation du retrait-gonflement des argiles

Abstract : The paper presents a new experimental device, developed in an Environmental Scanning Electron Microscope (ESEM), allowing to measure simultaneously the evolution of the surface strain of clayey aggregates and the evolution of their water content. The initial state of samples is in powder form, what allows making a complete cycle of wetting-drying in 24 hours, unlike the classic tests in the mesoscopic scale. The obtained results can be correlated in the profiles of evolution of the water content according to the depth workbenches in situ.
