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 ...
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 ...
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 ...
Curing stress effect on stability, microstructure, matric suction and electrical conductivity of cementitious tailings backfills
(Elsevier, 2022)
Cementitious tailings backfill (CTB) is a regularly used technique for most mines at home and aboard since it has a significant meaning for the recycling of total tailings and enhances the safety of underground mines. Thus, ...
Application of artificial neural networks in the analysis of the continuous contact problem
(Techno-Press, 2022)
This paper investigates the artificial neural network (ANN) to predict the dimensionless parameters for contact pressures and contact lengths under the rigid punch, the initial separation loads, and the initial separation ...
Strength and microstructure evolution in cemented mine backfill with low and high pH pyritic tailings: Effect of mineral admixtures
(Elsevier, 2022)
To properly dispose mining-induced tailings, diverse techniques including cemented paste fill (CPB) have been already employed. Indeed, tailings are manufactured by using different admixtures which are poisonous to the ...
Biomechanical analysis of odontoid and transverse atlantal ligament in humans with ponticulus posticus variation under different loading conditions: Finite element study
(Elsevier, 2022)
Purpose: Ponticulus posticus (PP) is a variation of the bone bridge that appears in the first cervical vertebra and through which the vertebral artery passes. Odontoid fractures are common spinal bone fractures
in older ...
Assessment of rheological and sedimentation characteristics of fresh cemented tailings backfill slurry
(Taylor & Francis Ltd, 2020)
Unreasonable choice of solid content (SC) and cement-to-tailings ratio (c/t), including pipeline networking system, will lead to some pipeline problems, such as blockage, wear, and rupture. Hence, this study deals with the ...
Determination of the pozzolanic activities of trachyte and rhyolite and comparison of the test methods implemented
(Springer International Publishing Ag, 2020)
Natural pozzolanas should be evaluated in terms of sustainability as well as their contribution to concrete durability. Therefore, the use of such materials in the production of cement as well as concrete industry has been ...
