Abstract
Results of a laboratory investigation on the effects of electro-osmosis on the permeability of kaolinite clay are presented. Application of an electric potential to the kaolinite clay increased the permeability of the clay and created a ph gradient across the sample. With application of combined electric and hydraulic gradients, electric gradients were found to contribute significantly to discharges across the sample at low hydraulic gradients. Results presented will enhance understanding as to the feasibility of using electro-osmosisto decontaminate fine-grained soils.
