        abstract = {The growing demand for sustainable construction materials has led to the development of geopolymer concrete (GPC) as an eco-friendly alternative to conventional Portland cement concrete. This study investigates the performance of Hybrid Fiber Reinforced Geopolymer Concrete (HFRGC) incorporating a combination of steel, polypropylene, glass, and flax fibers. The geopolymer matrix was formulated using industrial by-products such as fly ash and ground granulated blast furnace slag (GGBS), activated with alkaline solutions.
The primary objective of this research is to evaluate the mechanical properties of HFRGC, particularly compressive strength, split tensile strength, and flexural strength, under ambient curing conditions. An M20 grade mix was developed through trial mix optimization, and specimens including cubes, cylinders, and beams were prepared, cured for 28 days, and tested.
The study confirms that ambient-cured HFRGC is a viable and sustainable construction material with improved mechanical properties. The findings contribute to addressing existing research gaps related to multi-fiber hybridization and provide a foundation for further studies on durability and standardization of geopolymer composites.},
