Evaluation of the chemico-osmotic behaviour of a natural bentonite

Summary The paper presents an introduction to the chemico-osmotic phenomenon, which characterizes semi-permeable soils . Subsequently the preliminary experimental results relative to the chemico-osmotic behaviour of a natural bentonite, used in a manufactured geosynthetic clay liner (GCL), are reported. The results were obtained at Politecnico di Torino, using an innovative apparatus, reproduced on the basis of the design of Ghent University.
