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 ...
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 ...
The effect of capillarity on chloride transport and the prediction of the accumulation region of chloride in concretes with reinforcement corrosion
(Elsevier, 2012)
In this study, 20-year-old residential buildings which have reinforcement bar corrosion in their basement columns were investigated in Rize, Turkey. The reason for the occurrence of high steel corrosion in only some certain ...
