879 3.2.7 Large Scale Triaxial Testing - Phase 2 (IDIEM - Chile) Large-scale triaxial tests16 were carried out, thereby inferring the behavior of the mixtures when deposited in the dumps, with the aim of evaluating the geotechnical stability and compressive strength of the mixtures, which will be deposited in the dumps. It used intrusive and marble material (waste rock) and M4 (tailings) material at different mixed ratios: 2 : 1, 4: 1, 6: 1, and 8: 1; needed information for incorporating the segregation effect in the simulations works and models. Monotonic and Loading & Unloading testing were performed, whose results are shown below: Figure 10 – Large Shear stress vs axial deformation (Phase 2) 3.2.8 Large Diameter Kinetic Testing - Phase 2 (Canada) The same materials and mixture ratio were used as in large-scale triaxial testing to analyze the segregation effect in the geochemical models Figure 11. Large Diameter Kinetic Testing Results – pH 16 Diameter of 1.0 m and 1.8 m of height
