A wide laboratory investigation is presented in order to emphasize the effects of bentonitic clays and pore fluid on the hydraulic and mechanical properties of sand-clay mixtures. Oedometric, constant- and falling-head permeability and direct shear tests were performed on different plasticity mixtures, saturated alternatively with distilled water and inorganic leachate. Large fluctuations of permeability, compressibility and shear strength were observed.

Abstract
A wide laboratory investigation is presented in order to emphasize the effects of bentonitic clays and pore fluid on the hydraulic and mechanical properties of sand-clay mixtures. Oedometric, constant- and falling-head permeability and direct shear tests were performed on different plasticity mixtures, saturated alternatively with distilled water and inorganic leachate. Large fluctuations of permeability, compressibility and shear strength were observed.
