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
(Taylor & Francis Inc, Philadelphia, 2013)
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 ...
Drying kinetic simulation of clay tiles made from the raw material having less clay fraction
(Trans Tech Publications Ltd, 2014)
In order to describe the internal moisture rate and to take all different mechanisms of moisture movement into account, it is suitable to use effective diffusivity as a measure of moisture rate, irrespectively of the ...
