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 ...
Evaluation of the contact problem of functionally graded layer resting on rigid foundation pressed via rigid punch by analytical and numerical (FEM and MLP) methods
(Springer, 2022)
In this paper, frictionless contact problem for a functionally graded (FG) layer is considered. The FG layer is subjected to load with a rigid punch and the FG layer is bonded on a rigid foundation. Analysis of this contact ...
Strength analysis and optimization of alkali activated slag backfills through response surface methodology
(Frontiers Media, 2022)
The significant difference in water-to-binder ratio, activator type and concentration between alkali-activated slag (AAS) paste/mortar/concrete and AAS-based cemented paste backfill (AAS-CPB) means that previous results ...
Influence of 3D-printed polymer structures on dynamic splitting and crack propagation behavior of cementitious tailings backfill
(Elsevier, 2022)
Originally developed for polymer materials, 3D printing is an encouraging technique to create versatile geometric shapes and high-precision construction elements from various materials. 3D-printed polymer structures are ...
Effect of height to diameter ratio on dynamic characteristics of cemented tailings backfills with fiber reinforcement through impact loading
(Elsevier, 2022)
The safety and durability of underground backfilled stopes of metalliferous mines are so crucial owing to several dynamic events such as rock bursting, loads triggered by blasting, and loading conditions under stress. ...
Characterization of macro mechanical properties and microstructures of cement-based composites prepared from fly ash, gypsum and steel slag
(MDPI, 2022)
Using solid wastes (SWs) as backfilling material to fill underground mined-out areas (UMOAs) solved the environmental problems caused by SWs and reduced the backfilling cost. In this study, fly ash (FA), gypsum and steel ...
Strength, acoustic, and fractal behavior of fiber reinforced cemented tailings backfill subjected to triaxial compression loads
(Elsevier, 2022)
Overall, solid materials like CTB (i.e., cemented tailings backfill) give out low-level seismic signals as they are under stress in underground mining applications involving ground control, rock burst, and coal bump ...
