A process for modifying the physical characteristics of argillaceous soils

... 512,763. Electrolytic treatment of soil. RODIO, G. Nov. 26, 1937, No. 32730. Void. Convention date, Nov. 28, 1936. [Class 41] [Also in Group XXI] Physical characteristics of argillaceous soils are modified by injecting into the soil a liquid containing ions capable of substituting themselves for the ions present at the surface of the particles of clay and having an affinity for water different from that of the replaced ions. Thus, water may be freed from a clay rlch in sodium carbonate by injecting cement, free lime or an aluminium salt in solution or suspension, and the process may be assisted by treating the soil electrically, as by a continuous current using an aluminium electrode ; freed water may be left in situ or removed by electro-osmosis, or creation of a hydraulic gradient. Similarly, clay poor in Na2O may be consolidated by injecting caustic soda, sodium carbonate, sodium silicate &c. so as to increase the amount of water absorbed.
