Effects of Storage and Extrusion on Sample Properties

Source

The shear strength of specimens obtained with thin-walled tubes decreased as a result of long-term storage. The preconsolidation pressure of stored tube samples also followed a similar trend. Specimens obtained from hand-cut blocks did not show a decrease in strength or preconsolidation pressure with time. Samples stored by wrapping in plastic film and aluminum foil were found to be preserved as well as those stored after coating with paraffin. Stresses applied to samples for extruding from thin-walled tubes were found to be in excess of the shear strength of the soils. X-ray radiographs of specimens obtained with thin-walled tubes showed excessive disturbances caused by sampling and extrusion.
