Influence of types and contents of nano cellulose materials as reinforcement on stability performance of cementitious tailings backfill
(Elsevier, 2022)
This study explores the quality of cemented tailings backfill (CTB) reinforced with diverse nano cellulose materials (NCMs) such as micro-fibrillated cellulose (MFC), hydroxylated cellulose nanofiber (CNF), and cellulose ...
A joint experiment and discussion for strength characteristics of cemented paste backfill considering curing conditions
(MDPI, 2022)
As lots of underground mines have been exploited in the past decades, many stope instability and surface subsidence problems are appeared in the underground mines, while the cemented paste backfill (CPB) technology has ...
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 ...
Recycling dam tailings as cemented mine backfill: Mechanical and geotechnical properties
(Hindawi, 2022)
As a result of developing technology and scientific studies, employing dam tailings as critical raw material and vital economic reserve has become widespread recently. Employing dam tailings as a main ingredient of CPB ...
Mechanical and radiation attenuation properties of conventional and heavy concrete with diverse aggregate and water/cement ratios
(Croatian Association of Civil Engineers, 2022)
This paper presents the results of comprehensive laboratory work conducted for investigating the mechanical and radiation attenuation characteristics of heavyweight concrete produced with pyrite, chromium, and magnetite ...
Estimating the compressive strength of fly ash added concrete using artificial neural networks
(Manisa Celal Bayar Üniversitesi Fen Bilimleri Enstitüsü, 2022)
The aim of this study is to develop an artificial intelligence that predicts the compressive strength of fly
ash substituted concretes using material mixing ratios. Within the scope of the study, 5 different fly ash
mixed ...
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 ...
