Tertiary plutonic rocks of central and western Serbia Vardar zone as dimension stone
(Berg Fac Technical Univ Kosice, Kosice, 2013)
Five Tertiary granitoid plutons of central and western Serbia Vardar zone are examined in order to establish their potentiality for use as dimension stone. Field studies aimed at establishing the geological factors - ...
Characterization of New Structure for Silicon Carbide X-Ray Detector by Method Monte Carlo
(Polish Acad Sciences Inst Physics, Warsaw, 2011)
This work presents a characterization of radiation absorption properties of silicon carbide (SiC) as semiconductor for the realization of detectors for X-rays. SiC detectors can potentially reach superior performance with ...
Investigation of the mortar and concrete resistance in aggressive solutions
(Univ Osijek, Tech Fac, Slavonski Brod, 2014)
Testing the influence of two aggressive solutions - sulphate and nitrate on mortar and concrete was presented in this paper. Experimental work included testing of mortar prisms with 5 % special admixture. Also, four types ...
Chemometric Analysis of Alternations in Coal Ash Quality Induced by Application of Different Mechano-chemical Processing Parameters
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
The coal fly ash mechano-chemical activation conducted via high energy ultra-centrifugal mill was optimized using mathematical and statistical tools. The aim of the investigation was to accent the merits of alternations ...
Properties of composite cement with commercial and manufactured metakaolin
(Univ Osijek, Tech Fac, Slavonski Brod, 2013)
Metakaolin composite cements were prepared with 5 to 35 % replacement of ordinary Portland cement with metakaolin (MK), manufactured by thermal activation/calcination of domestic kaolin clay, and commercial matakaolin ...
Uticaj geometrije trna alata na mehaničke i strukturne karakteristike sučeonog spoja aluminijumske legure 2024-T351 zavarenog postupkom FSW / Influence of pin geometry on mechanical and structural properties of butt friction stir welded 2024-T351 aluminum alloy
(Savez hemijskih inženjera, Beograd, 2015)
U radu je ispitivano kakav zajednički, kombinovani uticaj brzina rotacije alata, brzina zavarivanja i mala promena u geometriji trna alata imaju na zavarljivost, mehaničke i strukturne karakteristike sučeonog spoja Al ...
Effect of welded joint imperfection on the integrity of pipe elbows subjected to internal pressure
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2013)
Since local defects reduce the load-carrying capacity and deformation ability of a piping system, an analysis is undertaken to quantify the influence of weld defects on integrity of the pipe elbows subjected to internal ...
