Abstract

Alternative binder materials for environmentally friendly building are being investigated in an effort to lessen the negative effects of the toxic emissions emitted during the manufacturing of Ordinary Portland Cement (OPC). Geopolymer Concrete (GPC), a potential invention that replaces cement with industrial waste, is one example. Numerous studies have determined that elements including fly ash, silica fume, ground granulated blast furnace slag (GGBS), and alcofines are useful ingredients for creating geopolymer concrete. When activated using alkaline solutions, GGBS, a byproduct of the steel industry, shows great promise as a single binder, producing a high-performance and long-lasting cement-free concrete. GGBS-based Geopolymer Concrete (GGC) reinforced with hybrid fibers—a blend of steel and polypropylene fibers—maintained at a total volume fraction of 1% of the binder is the major goal of the current investigation. The mechanical behavior of this Hybrid Fiber Reinforced Geopolymer Concrete (HFGGC) under flexure, tension, and compression was examined. The findings showed that polypropylene fibers improved the flexural performance while steel fibers greatly increased the split tensile strength. Improved strength, ductility, and durability resulted from the fibers’ synergistic impact, proving that GGBS-based geopolymer concrete is a viable and sustainable substitute for OPC concrete.
