Summary: This study investigated the effect of polypropylene (PP) fibers on the properties of modified magnesium-coal-based solid waste backfill materials (MFPB). It was found that increasing the content and length of PP fibers reduced the flowability of MFPB but significantly increased its strength. The permeability of MFPB initially decreased and then increased with the presence of PP fibers. The network structure formed by the PP fibers enhanced the strength and toughness of MFPB. This study provides valuable insights for the application of PP fibers in backfill mining.

Summary: This study investigates the effect of carbon nanotubes (CNTs) on the strength behavior of cementitious tailings backfill (CTB). The results show that CNTs significantly improve the strength and microstructure of CTB by inhibiting crack expansion and enhancing material integrity. Among them, ordinary multi-walled CNT (CNTPL) has the most significant impact on the mechanical properties of CTB. In conclusion, this study demonstrates that using the fractal properties of microstructure can better estimate the strength development of CTB specimens reinforced with different types of CNTs.

Summary: Hybrid fiber affects the structure and performance of concrete by altering the characteristics of air voids. The relationship between air void structure and concrete permeability and salt freeze-thaw resistance is quantitatively analyzed. The hybrid ST-PP fiber can enhance the compressive strength and splitting tensile strength of concrete after salt F-T cycles, but has a negative effect on concrete permeability. Total air-void content, number of air voids, and tortuosity are key factors influencing the permeability and F-T resistance of concrete.

Summary: This study explores the effect of using 3D printed polymeric lattice to reinforce cementitious tailings backfill on roof stability. The results show that U-shaped 3DPPL reinforcement significantly improves the flexural strength of CTB when the material types are OR and NY, while material type TR weakens it. Among different shapes and material types, rhombus and OR are found to be the best choices. U-shaped 3DPPL reinforced backfills exhibit better flexural deflection values compared to N-3DPPL reinforced ones.

Summary: This study demonstrates that the increase in loess percentage enhances the workability and setting time of LSGC paste. The UCS of LSGC increases with curing time, the loess gel in LSGC is sodium-aluminate-silicate-hydrate (N-A-S-H), while the slag gel is calcium-(aluminate)-silicate-hydrate (C-(A)-S-H). The optimal ratio for loess to slag is 1:1, resulting in qualified workability and setting time, a 28-day UCS of about 14.61 MPa, and a dense and stable microstructure.

Summary: Cemented paste backfill (CPB) is an environmentally sustainable way to utilize mine tailings, and replacing cement with secondary raw materials like granulated blast-furnace slag can reduce total CO2 emissions. The study found that partial substitution of cement with slag improves the strength of CPB, while total replacement reduces early strength but provides excellent strength and lower porosity over longer time intervals. These findings can be applied to develop more durable and environmentally responsible CPB recipes for gold mines with similar mineral composition and gold extraction methods.
