Abstract

Flocculated and dispersed slurries at about 4 times the liquid limit were consolidated either isotropically or anisotropically to various values of the maximum effective consolidation stress to obtain a wide range of fabrics extending from highly random to highly oriented. A comprehensive appraisal of the clay fabric at its various levels of organization was obtained by examining each sample with the combined use of scanning electron microscopy, optical microscopy, and X-ray diffractometry. The consolidation stresses were released from both isotropically and anisotropically consolidated samples, the clay blocks were removed from the slurry consolidometers, mutually orthogonal specimens were trimmed from the blocks, and a laboratory program of creep tests, triaxial and uniaxial compression tests, and direct shear tests was conducted to investigate the directional dependence of the mechanical properties. Several different mathematical models were developed and/or applied to characterize various aspects of the experimentally observed behavior.
