The influence of nano-silica and barite aggregate on properties of ultra high performance concrete
(Elsevier Sci Ltd, Oxford, 2016)
The development of building materials with improved characteristics and their application for increasing structure durability and sustainability is one of the goals in construction sector. The main objective of this paper ...
Durability of concrete with different types of cement
(Procema SA, 2016)
Adequate measures must be taken during the determination of the concrete composition for ensuring the durability of concrete exposed to an aggressive environment. The influence of the cement type on the freeze/thaw resistance ...
Cavitation damages morphology of high-strength low-alloy steel
(Faculty of Metallurgy, 2016)
This paper presents the research into behaviour of HSLA steel affected by cavitation. The parent material (PM) and simulated heat-affected zone (SHAZ) were studied. Ultrasonic vibratory cavitation test was performed in ...
Need to Improve the Natural Aggregate Resources Supply in the City of Belgrade (Serbia)
(Berg Fac Technical Univ Kosice, Kosice, 2016)
The City of Belgrade is the largest market for aggregates in Serbia but the production of natural aggregates is rather small, around five percent of total consumption. This reflects the geology of the City of Belgrade ...
Experimental examination of fatigue life of welded joint with stress concentration
(Gruppo Italiano Frattura, 2016)
This paper presents results of experimental examinations of stress concentration influence to fatigue life of butt welded joints with K-groove, produced from the most frequently used structural steel S355J2+N. One group ...
Effect of locally damaged elbow segments on the integrity and reliability of the heating system
(Institut za ispitivanje materijala, Beograd, 2016)
This paper presents the integrity and reliability evaluation of the heating system as a whole, based on results of metallographic tests performed on parent material and the ultrasonic measurement of wall thickness of elbows ...

(Gruppo Italiano Frattura, 2016)
This paper presents integrity and life estimation of turbine runner cover in a vertical pipe turbines, Kaplan 200 MW nominal output power, produced in Russia, and built in six hydro-generation units of hydroelectric power ...
Probabilistic analysis of bearing capacity of piles with variable parameters in cpt test and calculation according to the requirements
(Institut za ispitivanje materijala, Beograd, 2016)
A probabilistic concept for determining pile bearing capacity is presented, taking into account the variability of CPT test parameters and methodology of calculation according to the requirements of Eurocode 7 (EN 1997-1: ...
Integrity assessment of regulation system pipeline elements in hydroelectric generating set a6 of hydro power plant 'djerdap 1'
(Institut za ispitivanje materijala, Beograd, 2016)
Vertical Kaplan turbines with nominal power of 176 MW manufactured in Russia are installed in 6 hydroelectric generating sets at hydro power plant 'Djerdap 1' (Kladovo, Serbia). Most of the components are made of materials ...
Determination of damage and repair methodology for the runner manhole of Kaplan turbine at the hydro power plant 'Djerdap 1'
(Institut za ispitivanje materijala, Beograd, 2016)
Results of non-destructive testing of the Kaplan turbine runner manhole welded structure are presented, on the basis of which the repair methodology is defined. During repair, the welding technology for elements of the ...
