Study of Phosphates use in Electrochemical Treatment of Water-saturated Argillaceous Soils

This article covers laboratory and field studies dealing with interaction between phosphorus acid compounds and argillaceous soils when exposed to DC electrical field. The formulations and methods of electrolyte introduction are described which provide a uniform improvement of soils across the whole inter-electrode space. Determined maximal uniformity of improvement was demonstrated by the soil sample treated with 5% ZnO. The highest strength of 0.89 MPa in the anode zone and uniform soil improvement was reached using electrolyte with density of 1.12g/cm3.
