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. ...
Influence of the phase composition of refractory materials on creep
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
In this paper, the relationship between the creeping effect and mineralogical characteristics of the applied binding phase for various refractory materials (high-alumina materials, with high or low impurity content, tar ...
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 ...
