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, ...
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 ...
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 ...
Effect of PCA on nanosized ulexite material prepared by mechanical milling
(Springer Heidelberg, 2017)
Raw ulexite (U-3 mm) mineral used as a initial material was milled by using mechanical milling method, the milling time of which is from 0 to 8 h. Particle size, morphology, elemental and crystal structure measurements of ...
Geotechnical assessment of a slope stability problem in the Citlakkale residential area (Giresun, NE Turkey)
(Springer Heidelberg, 2017)
Because of the rapidly growing population, new settlement areas are required, and finding an appropriate location is always difficult, especially in mountainous areas. in these regions, efficient use of the existing ...
Geotechnical investigations and remediation design for failure of tunnel portal section: a case study in northern Turkey
(Science Press, 2017)
Mass movements are very common problems in the eastern Black Sea region of Turkey due to its climate conditions, geological, and geomorphological characteristics. High slope angle, weathering, dense rainfalls, and anthropogenic ...
Environmental effects of t-shaped groins built on the eastern black sea coast on shore protection
(Parlar Scientific Publications (P S P), 2017)
The construction of the double highway on the Black Sea Coast was initiated in 1998, completed in 2000. During the construction, T-shaped groins where were built to protect the shore. in this article, the contribution of ...
