A FEASIBILITY STUDY OF ELECTROKINETIC PROCESSES FOR STABILIZATION OF SOILS FOR MILITARY MOBILITY PURPOSES. REPORT NO. 4. LABORATORY INVESTIGATION OF ELECTROKINETIC TREATMENT OF CONSOLIDATED SOILS.
Abstract
The results of a laboratory investigation of the effects of electrokinetic treatment on the strength of consolidated samples of illitic and montmorillonitic soils are presented. The samples were remolded specimens of sifted illite and montmorillonite mixed with a manufactured quartz silt. Substantial increases in the strength of the treated samples were noted. These strength increases were associated with consolidation of the soil and with physical - chemical changes in the material. As a result of the latter, smaller strengths were found in some zones within the soil specimens than would have been expected from the final moisture content of the material. It was found that electrokinetic treatment is most beneficial when the ratio of energy input per unit volume of clay fraction is the greatest. From this it is concluded that electrokinetic treatment is probably most useful in soils with clay contents of between 5 and 20 percent. The coefficient of electrokinetic permeability was found to vary throughout the treatment period. An equation is suggested relating this coefficient to several soil index properties. (Author)
