Improvement of the durability of concrete by substitution of raw ground colemanite
(Elsevier, 2023)
This study investigated the effects of raw ground colemanite (GC) mineral on concrete strength and durability. Concrete mixtures were prepared at six replacement levels of GC (0%, 1%, 2%, 3%, 4% and 5%, by weight of cement). ...
Polypropylene fiber effect on flexural strength, toughness, deflection, failure mode and microanalysis of cementitious backfills under three-point bending conditions
(MDPI, 2023)
Cemented tailings backfill (CTB) is continually practiced in a large number of metallic mines for re-filling underground ore extraction areas. Re-filling these areas can boost the security of mining teams during construction. ...
Quantitative analysis of pore characteristics of nanocellulose reinforced cementitious tailings fills using 3D reconstruction of CT images
(Elsevier, 2023)
This study aims at analyzing the influence of contents and types of various nanocelluloses (e.g., CNF, CNC, and MFC) and intermediate microstructure on strength/fracture features of cementitious tailings backfill (CTB). ...
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 ...
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 ...
Investigation of clean energy production in drinking water networks
(Springer, 2024)
Viable renewable energy sources must be low-cost, easy to install, clean, and reliable if they are to meet the energy demand of urban or rural areas. Water is able to provide efficient sources of electrical energy among ...
Slag-based stabilization/solidification of hazardous arsenic-bearing tailings as cemented paste backfill: Strength and arsenic immobilization assessment
(Elsevier, 2024)
The widespread occurrence of toxic arsenic in sulfidic and non-ferrous waste tailings hinders its disposal as cement paste backfill (CPB). Alkali activated slag (AAS) has recently begun to be practiced as an alternative ...
Investigating the non-linear effects of breach parameters on a dam break study
(Springer, 2024)
When settlements are located close to a dam, it is important to accurately predict the breach peak flow and the time to reach the peak. Therefore, the prediction of dam breach properties is essential in dam break studies. ...
Polypropylene fiber's effect on the features of combined cement-based tailing backfill: Micro- and macroscopic aspects
(MDPI, 2024)
In undercut-and-fill mining, backfills show weak tensile strength and poor ductility properties since they act as artificial pillars to support stope roofs. Hence, the enhancement of the stability of mining structures and ...
