Polymer shape effect on damage evolution, internal defects and crack propagation of 3D-printed polymer-based cementitious backfill
(Elsevier, 2023)
The strength property and damage mode of cementitious tailings backfill (CTB) are governed by its structural characteristics in the presence of the microstructure/internal defect effects. However, this correlation is still ...
Enhancing flexural property and mesoscopic mechanism of cementitious tailings backfill fabricated with 3D-printed polymers
(Elsevier, 2024)
Backfill mining, one of the most common methods for removing hazardous tailings, is performed on cementitious tailings backfill (CTB), which can be employed to fully discard risky tailings while diminishing the ecological ...
Effect of magnetic induction intensity and steel fiber rate on strength improvement of cementitious filling composites
(Elsevier, 2024)
The underhand cut-fill backfill mining manner (UCFBMM) is widely employed in nonferrous metallic mines, and stability of the artificial backfill top plate directly determines the safety of operators and equipment, which ...
Reinforcing effects of polypropylene on energy absorption and fracturing of cement-based tailings backfill under impact loading
(Springer, 2024)
Polypropylene (PP) fiber-reinforced cement-based tailings backfill (FRCTB) is a green compound material with superior crack resistance and has good prospects for application in underground mining. However, FRCTB exhibits ...
