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 ...
2D- and 3D-FEM modeling of rock masses at the Şilenkar viaduct site (NE Turkey) with regard to bearing capacity
(Springer, 2021)
The aim of this research was to examine the bearing capacity features of the rock masses at the site of Şilenkar viaduct which is a part of the highway substitution project at the Yusufeli Dam construction in NE Turkey. ...
Reinforcement effect of polypropylene fiber on dynamic properties of cemented tailings backfill under SHPB impact loading
(Elsevier, 2021)
Dynamic loads such as blasting may lead to diverse levels of failure in cemented tailings backfill (CTB) under diverse strain rates and frequency spectral amplitudes. Hence, changes in dynamic properties of filling due to ...
Bending behavior and failure mode of cemented tailings backfill composites incorporating different fibers for sustainable construction
(Elsevier, 2021)
Mechanical characteristics of cementitious materials with fiber reinforcement are different from non reinforced cementitious materials. The influence of fiber type and content, solid content, and cement to-tailings ratio ...
The effects of freeze-thaw cycles and block size on the use of the Gümüşhane Granitoid (Gümüşhane/Turkey) as building stone
(Springer, 2021)
The present study aims to examine the usability of the Gümüşhane Granitoid as a building stone taking into consideration the short-term freeze-thaw cycles and mean block volume. A total of 180 specimens were used in the ...
Sodium silicate effect on setting properties, strength behavior and microstructure of cemented coal fly ash backfill
(Elsevier, 2021)
Representing an engineered mixture of coal fly ash, cement and water, cemented coal fly ash backfill (CCB) is typically employed for filling the openings created after coal excavation in the earth. A high rate of productivity ...
