Fiber reinforced cementitious tailings backfill (FRCTB) is progressively employed in mining industry due to its high strength/stiffness-to-weight ratio. However, the wide use of FRCTB technique requires further study practice many different types fibers, either alone or combination. In this regard, paper explores impact composite (glass-polypropylene) fibers on microstructure FRCTBs considering weak surface and pore characteristics. The fractures backfills were quantitatively analyzed by a non-destructive X-ray micro-computed tomography system which permits imagining interior microstructures via construction 3D volumetric data diverse spatial scales. Quantitative parameters cover percent surface, porosity, sphericity. distribution surfaces, pores, fissures bridging effect also based reconstruction technique. Adding increased percentage FRCTB's surface. greater glass fiber dose, larger Composite can lessen porosity. smallest porosity was 0.07% for PP contents 0.4wt.% 0.2wt.%, respectively. A rise dose causes volume 10-100mm3 content. Fibers have 0.1-100mm3 deteriorates shape type leading reduction sphericity pores. There clear correlation between patterns along height specimens. Weak surfaces pores are prone develop as fractures. limit crack expansion FRCTB. Lastly, presents time- cost-saving method analyzing microstructure.
