Properties of Some Kaolin-Based Model Clay Soils



Kaolin has been widely used both in fundamental studies of soil behavior and in physical model tests. However, the properties of pure kaolin are somewhat atypical of natural clay soils. In the first part of this paper we compare the mechanical properties of sedimented kaolin to median trends established from tests on natural clays and argue that artificial soils incorporating a substantial granular fraction reflect more closely the behavior of “destructured” real clays. In the second part we report a laboratory investigation of one particular mixture and describe the stress-strain behavior and strength properties observed in a series of K0 consolidated triaxial tests in which local strain instrumentation was used to better define the stiffness characteristics at small strains.
