Abstract
Preliminary results of an investigation focused on the influence of electrokinetic treatment on the mechanical and hydraulic behaviour of clayey soils are presented. The experimental programme aims at providing
a contribution to the sustainability of contaminant extraction or containment via electroosmosis. Changes in the hydraulic and mechanical properties of two illitic clayey
soils, subjected to a DC electric field, were investigated.
Samples of the two soils were subjected to electrokinetic filtration, for different periods of time, and under different
constant loads. Afterwards, they were tested under onedimensional compression to detect changes in stiffness and hydraulic conductivity due to the electrical treatment. After the application of a DC field for a few hours, a small reversible increment in the average soil stiffness was
observed, with respect to the untreated soil, while the hydraulic conductivity was not affected substantially.
Dramatic changes of the mechanical and hydraulic soil properties, correlated to changes of the soil pH, were observed following non-conditioned electrokinetic treatment with duration of the order of days.
