Rock pillars in rock engineering are affected by the stress concentration, which is uneven
and can lead to potential instability after loading disturbance. In this paper, considering the …

Mine tailings (MTs) are ore residuals after valuable metals were extracted during mineral
processing, which can be reused to produce the geopolymer concrete for construction and …

Rock masses contain various discontinuities such as flaws, cracks, join sets and more, each
significantly affect the crack initiation, propagation and coalescence patterns of new cracks …

Fracturing in quasi-brittle such as rock involves the development of an inelastic zone around
the pre-crack tip, also known as the fracture process zone (FPZ). The evolution of FPZ, while …

We performed laboratory-scale unconfined compression experiments on Barre granite
specimen with a single pre-existing flaw to study the evolution of tensile and shear cracking …

Transparent physical models of real rocks fabricated using three-dimensional (3D) printing
technology are used in photoelastic experiments to quantify the evolution of the internal …

Time-dependent rock deformation caused by the initiation and growth of fractures leads to
the weakening of the rock mass. Understanding the fracturing mechanisms involved in the …

Mine tailings-based geopolymer was proved to be successfully created with enhanced
strength for potentially construction and building materials applications. Through …

Pre-existing discontinuities act as the primary source of damage initiation processes in rock
masses, and consequently govern their overall deformational behavior. As laboratory tests …

Ore beneficiation processes produce huge quantities of waste rock in the form of tailings. For
dispersed remote artisanal mining sites that are unapproachable to strong construction and …
