AB  - Geopolymerization presents alkali activation of aluminosilicate material yielding the solid product called
“geopolymer”. Chemical composition of source material i.e. the Ca content, greatly influences the properties
of geopolymers. Hence, the aim of this research was to investigate the influence of source materials with
different chemical compositions (low grade bauxite and electric arc furnaces slag) on the compressive
strength of geopolymers. The results have shown that slag based geopolymers are characterized by higher
compressive strength in comparison to the bauxite based geopolymers.
AB  - Geopolimerizacija pretstavlja alkalnu aktivaciju alumosilikatnog materijala kojom se dobija čvrsti produkt
koji se popularno naziva geopolimer. Hemijski sastav polaznog materijala odnosno sadržaj Ca u velikoj
mjeri utiče na osobine geopolimera. Stoga je ovo istraživanje imalo za cilj da ispita uticaj polaznih sirovina
različitog hemijskog sastava (bijelog boksita i elektropećne šljake) na pritisnu čvrstoću geopolimera.
Rezultati su pokazali da se geopolimeri na bazi šljake karakterišu većom pritisnom čvrstoćom u odnosu na
geopolimere na bazi bijelog boksita.

AB  - 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.
AB  - 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.
