Water Content Relationships of a Sensitive Clay Subjected to Cycles of Capillary Pressures
This paper presents the results of an experimental investigation carried out to determine the volume change response of a sensitive clay subjected to cycles of air pressure in a pressure plate apparatus. Several clay samples of varying initial water content were used in the test program. It was found that at high air pressures initially soft clay specimens become less compressible than initially stiff clay specimens of comparable water content. In addition, the clay became unsaturated at a water content varying between 25 and 30%.
