Analyzing the microstructure of cemented fills adding polypropylene-glass fibers with X-ray micro-computed tomography
(Elsevier, 2023)
Fiber reinforced cementitious tailings backfill (FRCTB) is progressively employed in mining industry due to its high strength/stiffness-to-weight ratio. However, the wide use of the FRCTB technique requires further study ...
Monitoring sediment transport in certain harbor launches in the southeastern black sea
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Abstract: The problem of shoaling on coastal structures is the result of an event that occurs as part
of the natural cycle. In cases where shoaling cannot be detected or prevented, various economic
and operational problems ...
The effect of daylight saving time options on electricity consumption of Turkey
(Elsevier Ltd, 2010)
Most of the developed countries in the world use Daylight Saving Time (DST) as an energy conservation method. This study focuses on the effects of DST on electrical lighting in the buildings in Turkey. Turkey might adjust ...
Mechanical, energy evolution, damage and microstructural behavior of cemented tailings-rock fill considering rock content and size effects
(Elsevier, 2024)
Cemented tailings-rock fill (CTRF) is crucial for engineering intention and durability of re-filled stopes in deep underground mines. The current work examined the effects of fragment contents and sizes on the mechanical, ...
Upstream vortices of a sluice gate: an experimental and numerical study
(IWA Publishing, 2023)
This paper aims to explore the effects of a sill under a standard sluice gate on the development of the intake vortices. In total, 200 experiments were carried out. Sills with different shapes and widths were considered ...
Improving the pozzolanic reactivity of clay, marl and obsidian through mechanochemical or thermal activation
(Springer Link, 2024)
This research investigated the physicochemical properties and pozzolanic reactivity of mechanochemically and thermally treated clay, marl, and obsidian as supplementary cementitious materials (SCMs). The results suggest ...
Innovative mine backfill materials and structures
(Taylor & Francis Ltd., 2023)
The mining of natural resources forms three broad classes of mine waste: waste rock, tailings, and coal gangue.
Effect of aluminosilicate precursors and curing regime on physico-mechanical durability and microstructural characteristics of coral geopolymers (Cor-Geo): Cleaner production for coral islands
(Elsevier, 2023)
This study investigated the mechanical, durability, microstructure, carbon footprint and cost characteristics of
new-generation metakaolin-based geopolymer composites. Instead of GBFS, 25 % metakaolin was used, and 25 ...
A New index and control method of filling effect for cemented paste backfill in coal mines
(Taylor & Francis Ltd., 2023)
The scientific filling effect characterization is very important for backfill mining. A new filling effect index, the final backfill ratio (FBR), is proposed through experimental tests and theoretical analysis, and the ...
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 ...
