The effect of electro-osmosis on the chemical, physical andmechanical
behavior of a clay soil was investigated through laboratory tests. An
electro-osmotic apparatus was designed and fabricated with electrical
vertical drains (EVD) to measure the desired parameters. The results
showed that:The value of Ke decreases with treatment time and with
increasing the applied voltage. The efficiency factor (β) is dependent
on the applied voltage and it decreases with increasing the applied voltage.
The values of pH and EC of anode and cathode reservoirs are
changed during the treatment time and their variations are increased
with increasing the applied voltage. Increasing the liquid and plastic
limits decreases the liquid index leading to an increase in shear strength
of the soil.
