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 ...
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 ...
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, ...
Transition coefficients between compressive strengths of samples with different shape and size in mass concrete and use of weight maturity method in dam construction
(Ernst & Sohn, 2019)
Mass concrete (MC) is widely used in dam concretes due to their large aggregate grain diameters, low cement dosage, and low hydration temperatures. Monitoring of the hydration temperature and compressive strength is an ...
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 ...
