dc.description.abstract | Elektropećna prašina je nus proizvod koji se dobija pri pretapanju čeličnog otpada u elektropećima.
Obzirom da sdrži izvjesnu količinu silicijuma i aluminijuma može se smatrati potencijalnom sirovinom za
proces geopolimerizacije. Geopolimerizacija uključuje alkalnu aktivaciju čvrstog alumosilikatnog materijala
sa jako alkalno silikatnim rastvorom pri čemu se dobija proizvod koji se uspješno može koristiti u
građevinarstvu. Ovo istraživanje je imalo za cilj da ispita uticaj sastava alkalnog aktivatora tj. uticaj alkalnog
jona (Na+
ili K+
) na čvrstoću, mikrostrukturu i postojanost geopolimerana bazi ELPT u agresivnim
sredinma.Resultati su pokazali da se Na-geopolimeri karakterišu većom čvrstoćom ali slabijom postojanošću
agresivnim sredinama u odnosu na K-geopolimer. Mikrostruktura i Na- i K- geopolimera se karakteriše
prisustvom C-(A)-S-H gela koji sadrži i izvjesnu količinu alkalnog jona. | sr |
dc.description.abstract | Electric arc furnace slag (EAFS) is a by-product of steel scrap remelting in electric arc furnaces. It
contains a certain quantity of silica and aluminum so it may be considered as a possible source for a
geopolymerization process. Geopolymerization involves alkali activation of solid aluminosilicate materials
with highly alkali silicate solution yielding a new product which can successfully be applied in civil
engineering. The aim of this paper was to investigate the influence of alkali activator composition i.e.
influence of an alkali ion ( Na+
and K+
) on the strength, microstructure and durability of EAFS based
geopolymers in an aggressive environment. The results have shown that Na- geopolymers are characterized
by higher strength but lower durability, in comparison to the K-geopolymers. Microstructures of both, Naand K- geopolymers are characterized by the presence of C-(A)-S-H gel which incorporates some alkali ions. | sr |
