A series of tests were performed to characterise the undrained monotonic and cyclic response of integral
tailings, using CIU triaxial and isotropically consolidated cyclic triaxial tests at different confining stresses.
The samples were obtained from thickened tailings ‘manufactured’ and deposited in the laboratory at 72%
concentration of solid particles and from samples prepared through moist tamping. With this data, the
influence of the ‘fabric’ or sample preparation on the undrained monotonic and cyclic behaviour of the
tailings will be evaluated. Finally, the results indicate that the thickened tailings tested are susceptible to
