Effects of red mud additions on gangue-cemented paste backfill properties

To research the influence of red mud (RM) on gangue-cemented paste backfill (GCPB) properties, GCPB samples with different proportions of RM and Portland cement (PC) were prepared. The macroscopic strength and microstructure evolution of GCPB were analyzed by uniaxial compression tests, X-ray diffra...
