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, ...
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 ...
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. ...
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 ...
On the plane receding contact between two functionally graded layers using computational, finite element and artificial neural network methods
(Wiley, 2022)
The frictionless double receding contact problem for two functionally graded (FG) layers pressed by a uniformly distributed load is addressed in this paper. The gradation in the layers is assumed to follow an exponential ...
