Having fun at the GDS test facility today testing a customers sample prior to shipment. A 500mm diameter x 1000mm height aggregate sample (our largest sample to date) failing under load in our 250kN frame, with new effective stress application via internal vacuum rather than traditional triaxial cell and confining pressure. Several dynamic cyclic tests were done initially on the sample with the final shear carried out at 1% strain per minute and unloading cycle at 500kPa of axial stress. The video below is a time lapse of the test. More details to follow soon.
