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 ...
Effect of 3D printed skeleton shapes on strength behavior, stress evolution and microstructural response of cement-based tailings backfills
(Elsevier, 2024)
The inherent brittle behavior of cement-based tail backfill (CTB) poses some challenges that can significantly impact the safety and effectiveness of underground mining operations. Due to its propensity for abrupt and ...
Effect of content of defluorinated solid waste on macroscopic strength and microstructural evolution of cemented tail filling composites
(Elsevier, 2024)
Solid waste created by the ferrous mining industry has a major number of notable differences. The deficiency of recognition of solid waste features is the key factor limiting its discarding and reuse. In this paper, cemented ...
Geopolymer mortars having glassy materials considering mechanical and microstructural features
(Elsevier, 2024)
In comparison with ordinary Portland cements, geopolymer-based cements are now gaining prominence as an eco-friendly substitute to decline CO2 emissions in the course of OPC manufacturing. In this study, mechanical/microstructural ...
