  • Abstract:
  • In contemporary civil engineering, Geopolymer concrete (GPC) has emerged as an ecologically sound alternative to conventional Portland cement-based concrete, owing to its enhanced mechanical properties and diminished carbon footprint. This study focuses on formulating GPC by partially replacing fly ash with Ground Granulated Blast Furnace Slag (GGBS) and utilizing an alkaline activator solution comprising sodium hydroxide and sodium silicate. Both mortar cubes and concrete specimens underwent testing, with variations in alkaline solution molarities and fly ash/GGBS proportions. Ambient temperature curing was employed, and the mixture design was optimized for optimal workability and strength. Comprehensive assessments of compressive, tensile, and flexural strengths were conducted to systematically evaluate the performance of GPC specimens. The microstructure of GPC was analyzed using X-ray diffraction (XRD) to investigate the composition and morphology of the geopolymer (GPR) binder and its influence on concrete performance. A pull-out experiment was executed to assess the bond strength of GPC under diverse loading conditions. This research significantly contributes to the expanding knowledge base on GPC, furthering its application in sustainable building practices.
