Statement

Direct shear experiments were performed on 2 clay gouges (<2microns grain size) in a triaxial pressure vessel. Samples were sheared between two stainless steel sliders, with fluid/vacuum controlled via porous sintered discs. Tests were run under the following experimental conditions for each sample, at a confining pressure (Pc) of 60 MPa unless otherwise indicated: 1. Saturated with deionised water (80 MPa Pc, 20 MPa fluid pressure (Pf)); 2. At room humidity; 3. At room humidity with a vacuum applied to the sample assembly; 4. Vacuum oven dry (to 130ºC for 20 hours, then cooled to room temperature under vacuum); 5. Vacuum oven dry (to 130ºC for 20 hours, then cooled to room temperature under vacuum) with a vacuum applied to the sample assembly; 6. At room humidity, taken to 130ºC in the sample assembly under vacuum for ~20 hours and allowed to cool, and then run under vacuum.
