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 ...
Determination of the apparent porosity level of refractory concrete during a sintering process using an ultrasonic pulse velocity technique and image analysis
(Savez hemijskih inženjera, Beograd, 2010)
Concrete which undergoes a thermal treatment before (pre-casted concrete blocks) and during (concrete embedded in-situ) its life-service can be applied in plants operating at high temperature and as thermal insulation. ...
Prompt system redesign: Shifting to open source technology to satisfy user requirements
(ComSIS Consortium, 2010)
The paper describes a redesign project undertaken in a short period to adapt a software system to user needs. Additional goals of the project included a shift to Open Source software and the selection of technology to ...
Microstructural analysis as the indicator for suitability of weld repairing of the heat resistant Cr - Ni steel
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2010)
Metallurgical evaluation was performed on a fractured column tube of the reformer furnace in an ammonia plant. The tubes were manufactured from centrifugally cast heat resistant steel HK 40. Optical and scanning electron ...
Luženje potencijalno toksičnih elemenata iz kompozita na bazi otpadnih sirovina / Leaching of the potentially toxic pollutants from composites based on waste raw material
(Savez hemijskih inženjera, Beograd, 2012)
Odlaganje letećeg pepela dobijenog u procesu sagorevanja uglja u termo-elektranama predstavlja veliki rizik za prirodnu sredinu zbog mogućnosti luženja opasnih čestica kao što su toksični metali. Takođe, opasnost od ...
Synthesis and sintering of high-temperature composites based on mechanically activated fly ash
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Količina letećeg pepela koji se proizvodi i koja će biti proizvedena u godinama koje dolaze zahteva razvoj novih metoda recikliranja u kojima će biti upotrebljene značajne količine ovog otpadnog materijala. Mogućnost ...
Dobijanje metakaolina termičkim tretmanom kaolinske gline / Thermal treatment of kaolin clay to obtain metakaolin
(Savez hemijskih inženjera, Beograd, 2010)
U radu su prikazani rezultati istraživanja dobijanja metakaolina termičkim tretmanom domaće kaolinske gline. Polazna sirovina je bila kaolinska glina sa ležišta Vrbica (Aranđelovački basen), čiji je sadržaj kaolinita oko ...
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 ...
Study on impact properties of creep-resistant steel thermally simulated heat affected zone
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
The steam pipe line and steam line material, along with its welded joints, subject to damage that accumulates during operation in coal power plants. As a result of thermal fatigue, dilatation of steam pipe line at an ...
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 - ...
