Abstract

The osmotic, hydraulic and self-healing efficiency of bentonite-based barriers for the containment of subsoil pollutants is governed not only by the intrinsic chemico-physical parameters of the bentonite, but also by the chemico-mechanical state parameters. A theoretical framework has been set up that is able to describe the chemical, hydraulic and mechanical behavior of bentonites in the case of one-dimensional strain and flow fields. The proposed theoretical hydro-chemico-mechanical framework has been validated through a comparison with both the direct measurements of the arrangement of bentonite fabric.
