Résumé
In civil engineering, electro-osmosis is a technique used as a means of dehydration, treatment of fine soils for the improvement and remediation. It is also used in agriculture for the desalinization of soils. In this study, the effect of electro-osmosis on the properties of a fine soil of the Ain Nouissy-Mostaganem region under a difference of electric potential was analyzed. The objective is to study the behavior of the water flow and the modification of some parameters, such as the electrical conductivity, the pH and the Atterberg limits during and after the electrokinetic process. These parameters make it possible to understand and control the performance of this technique with respect to the treatment under consideration. Soil heating during this process was approached through the surface temperature, indicating a loss of relative energy when the voltage gradient exceeds an optimal value.
