Laboratory Strength Testing of Argillaceous Limestone Under Varying Saturation, Scale, Loading Rate, and Confinement Conditions
The Deep Geological Repository (DGR) concept is the proposed solution for the long-term storage of nuclear waste in Canada. While site selection processes are currently underway for high-level waste storage, a low and intermediate waste storage DGR is planned for development at depth in Kincardine, …

Sourcing the clay: Iron Age pottery production around Poole Harbour and the Isle of Purbeck, Dorset, UK.
… are characterised by the presence of elongated argillaceous inclusions and a low incidence of silt-sized quartz, with variability in the range of larger quartz grains. Thin sections of 105 clay samples revealed the silt content of the clays is greater than that of the pottery, suggesting potters …
