Experimental study of triaxial shear features of concentrated full tailings considering the effect of curing age

The strength evolution law of concentrated full tailings is closely related to the storage construction method, especially growth shear with curing age. This study aims investigate influence materials on and reveal change Therefore, we carried out a comparative triaxial test between pure different ages. results show that had 70.7% higher cohesion 10% larger internal friction angle (IFA) than at age 0 days. Moreover, cured for 3 days 170.2% 12.1% IFA In addition, 7 149.4% stress-strain curve exhibits significantly influenced by material gradually moved from strain hardening softening as increased, failure two steps. indicates specimen still has certain capacity despite having zone. entire instantly fails when exceeds capacity. this can be used scientific bases design surface structures tailings.
