Abstract
This study aimed to develop eco-friendly alkali-activated mixtures utilizing blast furnace slag (BFS) and unground sugarcane bagasse ash (SBA). One-part mixtures comprising BFS, SBA, and sodium metasilicate as dry materials were compared to conventional mixtures. Mortars and pastes were prepared with SBA replacement ratios up to 70%. At 3-days compressive strength, an increase for mixtures with 10% and 30% SBA was observed. The techniques of XRD, TG, FTIR and SEM were used to identify chemical and morphological changes caused by SBA incorporation. Utilizing raw SBA eliminated processes, saved power consumption and made employing this waste feasible.
