Abstract Details

2008, MS, University of Cincinnati, Engineering : Civil Engineering.
In the Greater Cincinnati area, the Kope formation and in particular Kope shale is problematic for engineers and geologists because of its ever-changing strength and durability properties. The purpose of this research was to collect Kope shale samples and preserve them by two different methods: one set was plastic wrapped and the other was waxed per ASTM standards. Unconfined compression, slake durability, jar slake, Atterberg limits, clay percent, free swell, and swell pressure tests were then conducted on these sample at selected time intervals (1, 5, 7, 30, 365 days). As the natural moisture content of the Kope shale samples decreased, an increase in these samples’unconfined compressive strength (UCS) was observed. Similarly, as the natural moisture content decreased the samples’ durability increased. The plastic wrapped samples lost moisture at a more rapid pace than did the waxed samples. As the samples aged and lost moisture with time their UCS and durability increased. Moisture content plays a key role in the strength and durability of this weak shale. How these samples are preserved and how long before they are tested critically affects the test results.
