Abstract:

Geopolymer concrete (GPC) is the most advanced concrete after OPC. GPC has many benefits, including increased strength and durability. Strong early age strength and ambient curing of GPC reduce construction time. Binders, alkali-activated solution, and curing affect GPC strength. When industrial byproducts like fly ash and ground granulated blast-furnace slag (GGBS) are added to GPC, it reduces carbon dioxide emissions, reuses waste, saves valuable land from becoming dump yards, and reduces costs. Energy used to extract raw materials is also reduced. GPC's strength, durability, mix design, fibre effect on mechanical properties, and structural performance are reviewed in this paper. Also highlighted is the development of high-strength GPC using fly ash with sodium hydroxide as an alkaline solution under oven curing. Trial-and-error methods are suggested for GPC development from different binder materials. Rangan's mix design is used for fly-ash GPC. Fibres also make GPC more ductile. The scope of future GPC research is also suggested.
