According to the abstract released by the Intellectual Property India: "The increasing environmental impact associated with the production of Ordinary Portland Cement (OPC) has driven significant research toward the development of sustainable alternative construction materials. Geopolymer concrete (GPC), synthesized through the alkali activation of alumino-silicate rich industrial by-products, offers a promising low-carbon substitute for conventional cement-based concrete. This study presents the development and performance evaluation of geopolymer concrete and steel fiber reinforced geopolymer concrete (SFRGPC) produced using Fly Ash and Ground Granulated Blast Furnace Slag (GGBS) as primary binder materials. An alkaline activator solution consisting of sodium hydroxide and sodium silicate was employed to initiate the geopolymerization process. Various mix proportions were developed by optimizing Fly Ash-GGBS ratios and steel fiber contents to enhance mechanical performance. The experimental investigation included evaluation of compressive strength, split tensile strength, and flexural strength at different curing ages. Durability properties such as water absorption, permeability, resistance to sulfate and acid attack, and chloride penetration were also examined to assess long-term performance under aggressive environmental conditions. Microstructural characterization was conducted using advanced analytical techniques to study the geopolymer gel formation, pore structure, and fiber-matrix interfacial bonding. The results demonstrated that the incorporation of GGBS significantly improved early-age strength, while the addition of steel fibers enhanced tensile capacity, ductility, and crack resistance. The developed SFRGPC exhibited superior strength and durability compared to conventional OPC concrete, highlighting its suitability for structural and infrastructure applications. This research confirms the potential of geopolymer-based fiber-reinforced concretes as sustainable, high-performance materials for modern construction."
