        abstract = {Geopolymer concrete has emerged as an environmentally friendly substitute for conventional Portland cement-based concrete, showcasing improved durability and a reduced carbon footprint. This research aims to investigate the impact of incorporating Nano silica and Nano alumina particles (0% to 5% of each material) on the compressive, split tensile, and flexural strength of geopolymer concrete over curing durations of 7, 14, and 28 days. The study involves the preparation of distinct geopolymer concrete blends by substituting a fraction of the binder materials with Nano silica and Nano alumina particles. The proportions of Nano silica and Nano alumina were varied while keeping the overall mixture uniform to maintain consistent workability. Fresh geopolymer concrete specimens were meticulously cast and compacted using established methods, followed by controlled curing processes. Mechanical properties were evaluated through compressive, split tensile, and flexural strength assessments conducted at the specified curing periods. Furthermore, for future investigation, the microstructure of the geopolymer concrete can be examined using scanning electron microscopy (SEM) to explore the influence of Nano silica and Nano alumina on the bond between the geopolymer matrix and aggregates. Results indicate that the inclusion of Nano silica and Nano alumina led to substantial improvements in the mechanical behaviour of geopolymer concrete. At all curing durations, the compressive strength of geopolymer concrete demonstrated enhancement with the addition of Nano silica and Nano alumina. The 28-day compressive strength displayed enhancements of strength of concrete for Nano silica and Nano alumina-modified mixes, respectively, in comparison to the control geopolymer concrete.},
