EFFECT OF SOLUTION COMPOSITION ON THE SWELLING OF EXTRACTED CLAY SOILS

FOR SOILS CONTAINING EXPANSIBLE MINERALS, THE SWELLING OF EXTRACTED SOIL CLAYS IN MIXED SODIUM CHLORIDE-CALCIUM CHLORIDE SOLUTIONS WAS WELL CORRELATED WITH RELATIVE HYDRAULIC CONDUCTIVITY OF THE SOIL TO THE SAME SOLUTIONS, AND WITH THEORETICAL INTERLAYER SWELLING BASED UPON A DOMAIN MODEL. IN THIS MODEL, MIXED NA-CA CLAYS WERE CONSIDERED TO CONSIST OF DISCRETE NA- AND CA-REGIONS, WITH ONLY THE NA-REGIONS SWELLING AT LOW SALT CONCENTRATIONS. IMPLICATIONS OF THE RESULTS WITH RESPECT TO SOIL HYDRAULIC CONDUCTIVITY CHANGES ARE DISCUSSED. /AUTHOR/
