Investigation on the flexural strength, failure pattern and microstructural characteristics of combined fibers reinforced cemented tailings backfill
(Elsevier, 2021)
The brittleness of the cemented tailings backfill (CTB) can easily cause collapse, which seriously threatens the safety of underground mining workers and equipment. Studies have shown that fibers can improve the ductility ...
Two-dimensional modeling of flood wave propagation in residential areas after a dam break with application of diffusive and dynamic wave approaches
(Springer, 2021)
In this study, a two-dimensional hydraulic routing model was applied to a sudden failure scenario for the Atasu Dam in Trabzon, Turkey. The goal was to simulate spreading and propagation of a dam break flood wave along a ...
Utilizing concrete pillars as an environmental mining practice in underground mines
(Elsevier Ltd, 2021)
Ground control is an integral element of mine design and worker safety. The use of concrete pillars for underground mines is of paramount importance to maintaining the economic and operational security of structures. This ...
Geopolymerization mechanism of binder-free mine tailings by sodium silicate
(Elsevier Ltd, 2021)
The geopolymerization of solid substances rich in calcium and aluminum including mine tailings by sodium silicate is mainly believed to be under the influence of alkali activation. However, mine tailings’ relative neutral ...
Influence of types and shapes of 3D printed polymeric lattice on ductility performance of cementitious backfill composites
(Elsevier, 2021)
The compression properties of cementitious backfill composite (CBC) is strong, but their tension properties are weak and presents little ductility because of their low fatigue crack growth rate and resistance. Thus, proper ...
Effects of mineral additives and age on microstructure evolution and durability properties of sand-reinforced cementitious mine backfills
(Elsevier, 2022)
Cementitious paste/mine backfill (CMB/CPB) is a creative way to proficiently decrease the sum of sulfidic tailings. However, considering them as minor raw material and inadequacies in their gradation, OPC (costly and ...
Physico-chemical and micro-structural behavior of cemented mine backfill: Effect of pH in dam tailings
(Elsevier, 2022)
The tailings created during ore processing have been a serious problem for mining companies and environment since it is a challenging task to effectively manage these highly voluminous/dangerous tailings. Therefore, several ...
Suture button fixation method used in the treatment of syndesmosis injury: A biomechanical analysis of the effect of the placement of the button on the distal tibiofibular joint in the mid-stance phase with finite elements method
(Elsevier, 2022)
Purpose: The purpose of this study is to research the effect of suture button (SB) fixation, a method used at the treatment of ankle syndesmosis injury, which was applied in various angles, pretension force, and levels, ...
The impact of mechanochemical activation on the physicochemical properties and pozzolanic reactivity of kaolinite, muscovite and montmorillonite
(Elsevier, 2022)
Partially replacing cement clinkers with activated clays is one of the most promising routes to decarbonise the cement industry and tackle the climate change crisis. This study systematically investigated the impact of ...
Finite element analysis of the mechanical behavior of the different angle hip femoral stem
(Techno-Press, 2022)
Femoral stems with proximal metaphyseal involvement are commonly used total hip replacement components with very good results. In this study, total hip arthroplasty (THA) application was analyzed using a three-dimensionally ...
