Meaning, measurement, and practical application of swelling pressure

Magnitude of swelling pressure and time-rate of swelling pressure development for Taylor shale material were investigated. A total of 227, 2.5 inch and 1.77 inch diameter Taylor shale specimens oriented both perpendicular as well as parallel to the bedding planes were tested in three types of loading frames, using four different methods of measurement of swelling pressure. A number of specimens were also tested after they were exposed to different drying environment in order to broaden the understanding of magnitude of swelling pressure and time-rate of swelling pressure development. Taylor shale material tested included M-1 Taylor shale with natural water content of 12 to 16% and plasticity index of 24 to 43%, M-0 Taylor shale with natural water content of 19 to 43% and plasticity index of 49 to 203%, and weathered Taylor shale with natural water content of 14 to 34% and plasticity index of 40 to 70%.
