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 ... -
Pozzolanic properties of trachyte and rhyolite and their effects on alkali-silica reaction
(Techno-Press, 2021)The alkali-silica reaction (ASR) is a highly complex chemical reaction which causes damage to concrete and thus adversely affects the durability and service life. Significant damage can occur in concrete structures due to ... -
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 ... -
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 ... -
Influence of industrial solid waste as filling material on mechanical and microstructural characteristics of cementitious backfills
(Elsevier, 2021)Use of industrial solid wastes (e.g., fly ash, desulfurization gypsum, steel slag) as mine fill material not only solves the environmental risks dictated by the sustainable management of these wastes, but also reduces the ... -
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 ... -
Analysis of tensile mechanical characteristics of fibre reinforced backfill through splitting tensile and three-point bending tests
(Taylor & Francis Ltd., 2021)The cut-and-fill mining method is used in metalliferous mines thanks to backfilling instead of ore pillars. However, the stability of the artificial cemented tailings backfill (CTB) roof is one of the key influencing factors ... -
Analyzing the contact problem of a functionally graded layer resting on an elastic half plane with theory of elasticity, finite element method and multilayer perceptron
(Techno-Press, 2021)This paper presents a comparative study of analytical method, finite element method (FEM) and Multilayer Perceptron (MLP) for analysis of a contact problem. The problem consists of a functionally graded (FG) layer resting ... -
Assessment of different solution methods for receding contact problems in functionally graded layered mediums
(Elsevier, 2021)This paper presents a comparative study of different methods, such as the analytical method, finite element method (FEM), and multilayer perceptron (MLP) for analyzing a frictionless receding contact problem. The problem ... -
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 ... -
Investigation of continuous and discontinuous contact cases in the contact mechanics of graded materials using analytical method and FEM
(Techno-Press, 2021)The aim of this paper was to examine the continuous and discontinuous contact problems between the functionally graded (FG) layer pressed with a uniformly distributed load and homogeneous half plane using an analytical ... -
Stability investigation of a deep shaft using different methods
(ASCE- American Society of Civil Engineers, 2021)The New Zigana Tunnel is, at 14.5 km long, the longest highway tunnel project in Turkey. In this project, it is planned to construct two service shafts to provide access to outside the tunnel and temporary ventilation. ... -
The durability of high-strength concrete containing waste tire steel fiber and Ccal fly ash
(Hindawi, 2021)The demands for high-strength concrete (HSC) have been increasing rapidly in the construction industry due to the requirements of thin and durable structural elements. HSC is highly brittle. Therefore, to augment its ... -
Analysis of strength and microstructural characteristics of mine backfills containing fly ash and desulfurized gypsum
(MDPI, 2021)The utilization of solid wastes (SWs) as a potential resource for backfilling is not only conducive to environmental protection but also reduces the surface storage of waste. Two types of SWs, including fly ash (FA) and ... -
A large goaf group treatment by means of Mine Backfill Technology
(Hindawi, 2021)There are few studies on the management methods of large-scale goaf groups per the specific surrounding rock mass conditions of each goaf. This paper evaluates comprehensively the stability of the multistage large-scale ... -
A solution to the time-dependent stress sistribution in suborbicular backfilled stope interaction with creeping rock
(Hindawi, 2021)The creep behavior of deep weak rock masses is important due to an underground opening. Appreciating the nature and source of these deformations requires the knowledge of rock mass and ground support interaction. The ... -
Characterization of strength and quality of cemented mine backfill made up of lead-zinc processing tailings
(Frontiers Media, 2021)Predicting the reactions of the backfill materials exposed to the effects of air and groundwater will eventually ensure an efficient and accurate mine fill system for sustainable mining operations. This paper reveals the ... -
