Environmental sustainability is a paramount concern worldwide, and addressing issues such as the depletion of river sand and the underutilization of fly ash has become imperative. India, in particular, disposes of a staggering 38 million tons of fly ash annually. This study focuses on harnessing the potential of fly ash through the development of Geopolymer Fly Ash Fine Aggregate (GFAFA) and its incorporation into mortar as a fine aggregate. Various characteristics of GFAFA including particle size distribution, specific gravity and surface morphology are analyzed to assess its suitability as a construction material. The particle size distribution analysis demonstrates that GFAFA falls within the prescribed limits suitable for mortar usage. Moreover, the specific gravity of GFAFA is 2.1, presenting a notable contrast to the specific gravity of M-sand (2.68). Field Emission Scanning Electron Microscopy (FESEM) image of GFAFA corroborates the presence of surface porosity and unreacted fly ash particles. The study investigates the effects of partial replacement of M-sand with GFAFA on mortar properties, such as unit weight and compressive strength. The results indicate that a 30% replacement of M-sand with GFAFA yields the highest compressive strength, suggesting this as the optimal substitution ratio in mortar mixtures.
