Abstract

The objective of this research was the study of the long-term effects of temperature variations on the volume and texture of clayed soils, notably as a function of their initial petrophysical and petrographical characteristics and their pre-consolidation state. From the experimental point of view, the study was based on the observation of the volumetrical deformation of samples subjected to thermal loading within the temperature range 20 to 110 C with periodical measurements of their permeability in an oedometric cell. A complete textural study (mercury porosimetry and observations under a scanning electron microscope) before and after the experiments allowed continuous monitoring of the evolution of the texture.
