Environmental influence on service life expectancy of ceramic structures
(Политехпериодика/Politehperiodika, 2015)
During the service life, materials are exposed to environmental influences. The aim of this research is to analyze behavior of sulfur concrete compared to Portland cement concrete in acid environment. It has been shown ...
Energy efficient pulse-reverse regimes of electrodeposition / Energetski efikasni pulsno-reverzni režimi galvanizacije
(Union of Mechanical and Electrical Engineers and Technicains of Serbia (SMEITS)Society for Renewable Electrical Power Sources, 2017)
Pulse reverse power modes are used in order to obtain metal coatings with similar or better characteristics, compared with the coatings produced by constant current. Pulse reverse modes increase production and energy ...
Damage level evaluation of zircon samples caused by cavitation erosion using image analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2017)
This study is focused on monitoring the degradation level of zircon based ceramic materials during exposure to cavitation. In addition to conventional degradation monitoring methods, weight loss measuring, the emphasis is ...
Cavitation damage of mullite ceramic: implementation of image analysis
(Bor : University of Belgrade - Technical Faculty in BorBor : Mining and Metallurgy Institute Bor, 2016)
The paper presents the results of testing the mullite ceramics in terms of cavitation erosion. Mullite samples were sintered at 1200 °C. To determine the cavitation resistance the ultrasonic vibration method with stationary ...
Valorization of secondary sulfur from oil refining process for sulfur concrete production
(Bor : University of Belgrade - Technical Faculty in Bor, 2015)
Modification of conventional building materials is commonly realized using different waste materials. In this research, the use of secondary sulfur as binding agent in concrete was analyzed. Sulfur concrete is a thermoplastic ...
Application of polymer materials for production of evaporative pattern and development of new casting process
(Bor, Srbija : Tehnički fakultet Bor, Institut za rudarstvo i metalurgiju, 2012)
In this paper, results of the investigation of the polymer materials for evaporate patterns and their application in the new casting method (EPC process) are presented. The basic characteristic of EPC process is that ...

Heavy metals in soils of Srem (Vojvodina)
(Bor : University of Belgrade-Technical Faculty in Bor, 2017)
Potentially harmful trace elements pollution in soils is a worldwide environmental problem that has received increasing attention over the last few decades because of its adverse effects. Metals in soils are present in ...
Anisotropy of refractory concrete subjected to the thermal shock by using the surface analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Monitoring and analysis of the material anisotropy during the thermal shock of the refractory concrete was studied. The material was alumina based low cement castable pre-treated at 1300°C for 3 hours. Water quench test ...
Adsorption properties of TENT fly ash in removal of copper from wastewater
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
The objective of this study was to monitor the behavior of fly ash originated from the power plant Nikola Tesla as a low cost absorbent for removal of copper ions from synthetic aqueous solutions. Fly ash, a potentional ...
