Abstract	This study investigates the performance of Geopolymer Concrete (GPC) synthesized from fly ash and GGBS, modified with silica fume and nano-silica. Experimental results indicate that the integration of nanomaterials refines the microstructure and accelerates the formation of N-A-S-H and C-A-S-H gels. The optimized mixes demonstrated a 15–35% increase in compressive strength and a 20–40% improvement in durability indicators, including acid and sulfate resistance. These findings position nano-modified GPC as a high-performance, low-carbon alternative to traditional cement.
