A fine-grained soil stock was cleaned of organic matter and soluble salts. then the slurry was repeatedly washed with a barium-chloride solution to ensure a known pore solution chemistry. Test specimens were prepared by first consolidating the slurry in triaxial cells under varying cell pressures, and secondly by trimming the specimens to be placed into electroosmotic cells enclosed in rubber membranes with the same confining pressure applied on the membrane as had been used in the consolidation phase. The electroosmotic treatment was performed at constant voltage gradient and was continued until the electrical conductivity of the effluent was similar to that of deionized water. The “postmortem” investigations of the treated specimens show that the confining pressure has a significant effect on the removal of barium by the electroosmotic treatment.
