Rheological properties of cemented paste backfill with alkali-activated slag
(Mdpi, 2020)
This study investigates the time-dependent rheological behavior of cemented paste backfill (CPB) that contains alkali-activated slag (AAS) as a binder. Rheological measurements with the controlled shear strain method have ...
Strength development and microstructure characteristics of artificial concrete pillar considering fiber type and content effects
(Elsevier Sci Ltd, 2020)
The artificial concrete pillar (ACP) replacement technique is a safe and reliable method to safely mine orebody pillar in room and pillar mining. in contrast to traditional ore pillar, artificial pillar has recently received ...
Fiber length effect on strength properties of polypropylene fiber reinforced cemented tailings backfill specimens with different sizes
(Elsevier Sci Ltd, 2020)
The strength properties of cemented tailings backfill (CTB: an engineered mix of processing tailings, hydraulic binder and mixing water) is strongly affected by its structural integrity. However, our understanding of the ...
Exploring the link between ultrasonic and strength behavior of cementitious mine backfill by considering pore structure
(Elsevier, 2023)
Understanding the porosity/pore linkage and strength properties of cementitious mine backfill (CMB) is essential for the design of underground mining filling. Adoption of new production techniques in parallel with the ...
Study of early-age performance of cementitious backfills with alkali activated slag under internal sulfate attack
(Elsevier, 2023)
The vulnerability to internal sulfate attack of calcium-rich ordinary Portland cement (OPC) and its relative high cost force mines to explore technically effective and low cost alternative binders to solidify sulfate-containing ...
Effect of content and length of polypropylene fibers on strength and microstructure of cementitious tailings-waste rock fill
(MDPI, 2023)
The mechanical strength properties of cemented tailings backfill are very important for the safe and environmentally friendly mining of mineral resources. To check the impact of polypropylene fiber on strength and ...
Long-term ageing characteristics of cemented paste backfill: Usability of sand as a partial substitute of hazardous tailings
(Elsevier, 2023)
Considering environmental problems caused by sulfidic tailings as a result of long-term ageing as well as inadequacies in their gradations in ensuring the strength needed for cemented paste backfill (CPB), there is a need ...
Curing conditions effect on pore structure, compressive strength and elastic modulus of cementitious tailings backfills
(Elsevier, 2023)
As a widespread application in underground metal mines, cementitious tailings backfill (CTB) has a significant implication for recycling dangerous process tailings and enhancing the safety of mining voids. The pore structure ...
Microstructure and mechanical behavior of cemented gold/tungsten mine tailings-crushed rock backfill: Effects of rock gradation and content
(Elsevier, 2023)
Without appropriate and responsible waste management in place, the cursory storage of tailings and waste rocks on the surface can cause devastating damage to the planet's ecosystems. To proactively manage or abolish the ...
