Sažetak
In this work, at the preparation of concrete as a binder instead of Portland cement was used alkali-activated fly ash. Sodium hydroxide and water glass were used as alkali activators. Fractions of natural aggregate of 0-4 mm, 4-8 mm and 8-16 mm are replaced by air-cooled granulated steel slag fraction of 4-8 mm and 8-16 mm and the fraction of river sand is replaced with silica fume. The obtained samples were cured at 2 different temperatures. The first was cured at room temperature and the other was steam-cured for 8 hours and leave at room temperature until the tested date. The compressive strength test was investigated by using cube samples 150 ×150 ×150 mm after 3 and 28 days. The results of the present work have shown that low-calcium fly ash-based geopolymer concrete can substitute the use of Portland cement in concrete.
