Role of Interparticle Forces in Development of Upper Plastic Limit of Clays

Abstract

THE standard laboratory test method in soil mechanics for determination of the liquid limit of clays (upper plastic limit) depends on the facility of movement of particles relative to one another under conditions created by the test procedure. An interpretation of the upper plastic limit of clays has recently been suggested1 in terms of distance between particles or structural units of particles wherein forces of interaction become sufficiently weak to allow slipping to occur.
