Effect of mineral admixtures on flow properties of fresh cemented paste backfill: Assessment of time dependency and thixotropy
(Elsevier, 2020)
Cemented paste backfill (CPB), an engineered mix consisting typically of tailings, cement and water, has become a regularly used structural material in most mines worldwide. the performance of the CPB structure is dependent ...
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 ...
Thermal insulation and mechanical properties of a specially improved insulation plaster under freezing-thawing and high-temperature conditions
(Oxford University Press, 2023)
In this study, the effects of heat preservation and the resistance to environmental conditions of ready-made insulating sludge used in the interior and exterior facades of the buildings were investigated. The insulation ...
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 ...
Performance based assessment of a small-scale artificially nourished beach
(Elsevier, 2023)
In coastal engineering studies, coastal protection procedures can be provided by hard and soft methods. Soft methods applied using the right techniques and methods are not only long-lasting but also adapt to the natural ...
Experimental performance assessment of a novel insulation plaster as an energy-efficient retrofit solution for external walls: A key building material towards low/zero carbon buildings
(Elsevier, 2023)
Thermal insulation plasters have become the focus of attention in the building sector. Among the most important reasons for this is the high thermal energy losses of the buildings. Since conventional briquettes used in ...
