Strength analysis and optimization of alkali activated slag backfills through response surface methodology
(Frontiers Media, 2022)
The significant difference in water-to-binder ratio, activator type and concentration between alkali-activated slag (AAS) paste/mortar/concrete and AAS-based cemented paste backfill (AAS-CPB) means that previous results ...
Characterization of macro mechanical properties and microstructures of cement-based composites prepared from fly ash, gypsum and steel slag
(MDPI, 2022)
Using solid wastes (SWs) as backfilling material to fill underground mined-out areas (UMOAs) solved the environmental problems caused by SWs and reduced the backfilling cost. In this study, fly ash (FA), gypsum and steel ...
Editorial: Advances in the design and implementation of cementitious backfills
(Frontiers Media, 2022)
Backfill plays an essential role in the most modern mining industries worldwide. It is usually applied
in the cementitious form to fill underground mined-out openings (stopes and/or voids)
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 ...
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 ...
Consolidated effect of fiber-reinforcement and concrete strength class on mechanical performance, economy and footprint of concrete for pavement use
(Elsevier, 2021)
The advancement in the tensile strength and ductility of plain concrete can minimize the quantity of materials required per unit strength to build eco-friendly structures. This paper compares the compressive and flexural ...
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 ...
The effect of occupational choice on job satisfaction and occupational accidents in the construction sector: A case study on Rize and Çorum in Turkey
(Dynamic Academy Yazılım İnşaat San. Tic. Ltd. Şti., 2021)
The construction sector is a sector that employs a significant amount of employees in Turkey and appeals to
many branches of work and professions. In Turkey, the construction sector ranks first in the statistics ...
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 ...
