Because sustainability is now a main priority, the construction industry is seeking new adhesives and recycled materials. The aim of this paper is to look at optimizing geopolymer concrete when it includes fly ash, ground granulated blast furnace slag (GGBFS) and recycled aggregates (RA). Through alkali activation, binders from industrial materials help make geopolymer concrete which is both green and replaces traditional Portland cement. Adding recycled aggregates makes the project even more sustainable. Experiments were carried out to measure the effects of binder ratios, the molarity of alkaline activators and RA content on strength and toughness. The investigators determine the optimal ratios that make construction stronger, use less carbon and support environmentally friendly construction. The findings are intended to give engineers and researchers helpful advice on improving geopolymer concrete for use in structures.
