Effects of electrochemical treatment on selected physical properties of a clayey silt

Experimental results which the authors have obtained show that electrochemical treatment using iron pipes for both the anode and the cathode can have a pronounced stabilizing effect on clayey silt. Soils were strengthened as a result of application of direct electrical current together with the introduction of calcium chloride, followed by aluminum sulfate. Increases in cohesion of the order of 150–500 lb/sq. ft. are possible. The beneficial effects were not reduced by subsequent water encroachment. Formation of new minerals in former voids and resulting cementation of the treated soil appears to be the main factor causing increased soil density and cohesion.
