(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 ...
Procena troškova rehabilitacije i rekonstrukcije u sistemima za upravljanje održavanjem puteva / Model development for the preliminary cost estimates of road rehabilitation and reconstruction works
(Srpsko društvo za puteve VIA-VITA, Beograd, 2012)
Prosečni jedinični troškovi radova u projektima rekonstrukcije i rehabilitacije (RiR) puteva se značajno razlikuju među državama, ali i u okviru različitih projekata u istoj državi, i to usled mnogobrojnih faktora. U okviru ...
Geopolimeri na bazi alkalno aktiviranog elektrofilterskog pepela kao novo vezivo u betonu / Alkali activated fly ash geopolymers as a new binder in concrete
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2013)
U skladu sa rastućom brigom za zaštitu životne sredine i potrebom razvoja održivog građevinarstva, javlja se i veće interesovanje za istraživanja u oblasti novih materijala, koji će koristiti otpadne sirovine i imati manji ...
Process parameters influence on microstructural properties of hypereutectic al-18wt% Si alloys obtained by rheocasting process
(Editura Stiintifica Fmr, Bucharest, 2012)
Hypereutectic Al-18wt%Si alloy was obtained by conventional and rheocasting procedure at cooling rate 0.16 +/- 0.05 degrees Cs-1. Samples of rheocasted alloy were obtained at two stirring speeds 1000 and 1500 rpm. Tests ...
Evaluation of Lignite Fly Ash for Utilization as Component in Construction Materials

Utilization potential of fly ash, as the main residue in the lignite coal combustion in Serbian power plants, was investigated in present study. High production of fly ash represents extreme hazard for environment. Question ...
Opekarske gline iz Srbije - primena u proizvodnji grube keramike / Serbian heavy clays behavior: Application in rough ceramics
(Savez hemijskih inženjera, Beograd, 2013)
Gline i glineni minerali se, usled mnogih specifičnih osobina pre i nakon pečenja, decenijama koriste kao osnovni materijali za proizvodnju grube keramike. Proučavanje i utvrđivanje mineralnih faza koje su prisutne u ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
Otpornost materijala na bazi metalurškog cementa na dejstvo kiselina / Resistance of CEM III/B based materials to acid attack
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
Cementni materijali u poljoprivrednim i drugim industrijskim objektima izloženi su dejstvu kiselina. Zbog toga vek konstrukcija zavisi od trajnosti maltera ili betonskih elemenata u agresivnoj sredini. U radu je predstavljena ...
