Impacts multi-échelles d'un échange (Mg, Ca)-Pb et ses conséquences sur l'augmentation de la perméabilité d'une bentonite.
Abstract
The article addresses the structural effects of solutions of lead nitrate on a suspended or compacted bentonite. A permeability increase is observed on compacted clay. Investigating the composition of output solution, using X-Rays Diffusion at Small Angles and Scanning Electron Microscopy, this permeability increase is explained from structural variations at nanometric (reduction of particle size) and micrometric scales (microfissuration of aggregates).
