THE CONDITION OF WATER IN POROUS SYSTEMS

Abstract

The condition of water in porous systems is discussed on the basis of (a) the phase diagram of water as worked out by Tammann and Bridgman and (b) the concept that internal pressures may be assumed to produce the same type of results as external pressures. Data taken from the literature and data obtained by the author on the behavior of a water-saturated Putnam clay when consolidating under pressure are employed as exptl. illustrations of the major points brought out by this method of attack. It appears that the employed concept leads to a ready explanation of a number of phenomena which are of practical importance in the stress-strain relationship of soil-water systems and of other porous hydrophilic systems.
