Fly Ash and GGBS-based Geopolymer Concrete and Its Water Absorption Capacity: A Comparative Study with Conventional Concrete

Geopolymer concrete (GPC) has emerged as a promising alternative to conventional concrete (CC) made with Portland cement. GPC has Fly ash and GGBS in a 70:30 ratio along with alkali activators Sodium hydroxide (NaOH) and sodium trisilicate (Na₂SiO₃). This study focuses on a comparative analysis of the water absorption capacity of GPC and CC. The results from the comparative study deduce that both types of concrete perform equivalently in terms of strength and durability, with slight differences in water-absorbing characteristics. The study suggests that further research and development are essential to further optimize GPC's properties and expand its applications in diverse construction scenarios. The findings are expected to demonstrate the potential for GPC to offer enhanced durability and reduced environmental impact, thereby supporting the transition toward more sustainable construction practices.
