VOLUME CHANGES IN SWELLING CLAYS

A THERMODYNAMIC DESCRIPTION OF SWELLING BY A CLAY-WATER-AIR SYSTEM IS PRESENTED. IT IS SHOWN THAT THIS DESCRIPTION, AT CONSTANT TEMPERATURE, IS IDENTICAL WITH THE MECHANICAL THEORY OF SWELLING DEVELOPED BY PHILIP. A NEW RELATIONSHIP IS DERIVED WHICH SHOWS THE CONNECTION BETWEEN THE SHRINKAGE CURVE, THE LOAD LINE, THE SWELLING PRESSURE, AND THE COMPRESSIBILITY OF A CLAY AT ANY WATER CONTENT. THIS RELATION IS APPLIED TO THE PRESSURE-CHAMBER DATA OF ANDERSON AND LOW TO COMPUTE THE PARTIAL DENSITY OF WATER ADSORBED BY NA-MONTMORILLONITE.
