Determination of natural radioactivity levels of some concretes and mineral admixtures in Turkey
(Asian Journal of Chemistry, 2014)
Nine concrete samples with or without mineral admixtures have been analyzed for their naturally occurring radionuclide of Ra-226, Th-232 and K-40 using HPGe gamma spectrometry. Also, concrete raw materials such as aggregate, ...
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 ...
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

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 ...
Comparing the pozzolanic activity properties of obsidian to those of fly ash and blast furnace slag
(Elsevier Sci Ltd, 2018)
The use of pozzolan in cement provides economic advantages and improves the physico-mechanical properties of cement. Fly ash and blast furnace slag are widely used in cement as pozzolanic materials. in this study, obsidian ...
Radiation shielding properties of mortars with minerals and ores additives
(Elsevier Sci Ltd, 2019)
Incorporation of mineral and ores as fine aggregate additives was investigated for its effect on the neutron and gamma-ray shielding properties of cement mortar. Five mortar mixtures have been prepared with different ...
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 ...
Thermal insulation and mechanical properties of a specially improved insulation plaster under freezing-thawing and high-temperature conditions
(Oxford University Press, 2023)
In this study, the effects of heat preservation and the resistance to environmental conditions of ready-made insulating sludge used in the interior and exterior facades of the buildings were investigated. The insulation ...
Experimental performance assessment of a novel insulation plaster as an energy-efficient retrofit solution for external walls: A key building material towards low/zero carbon buildings
(Elsevier, 2023)
Thermal insulation plasters have become the focus of attention in the building sector. Among the most important reasons for this is the high thermal energy losses of the buildings. Since conventional briquettes used in ...
