        abstract = {Concrete, though the most widely used construction material, is limited by low tensile strength and brittle failure. To address these shortcomings, this study investigates the combined incorporation of Nano Silica (NS) and Polypropylene Fibers (PPF) in M40 grade RCC beams. Nano Silica, owing to its ultrafine pozzolanic properties, enhances the microstructure and strength, while Polypropylene Fibers improve ductility, toughness, and crack resistance. The research analyzes the flexural behavior of RCC beams and compares conventional and modified beams in terms of first crack load, ultimate load, and deflection. To determine the optimum mix, concrete specimens including cubes, cylinders, and prisms were cast with a constant 2% NS and varying PPF dosages (0.25%, 0.5%, 0.75%, and 1%). Mechanical properties such as compressive, tensile, and flexural strengths were evaluated at 7, 14, and 28 days. The findings reveal that the optimum performance was achieved with 2% NS and 0.25% PPF, resulting in notable improvements in compressive, tensile, and flexural strength compared to conventional concrete},
