This research investigates the effects of incorporating bagasse ash, steel fibers, and polypropylene fibers on the mechanical properties of concrete. Bagasse ash, a byproduct of sugarcane processing, is explored as a partial replacement for cement, aiming to enhance sustainability while reducing waste. The addition of steel and polypropylene fibers is examined for their potential to improve tensile strength, toughness, and crack resistance. Concrete mixes with varying percentages of bagasse ash (up to 30%), steel fibers (0.5% and 1%), and polypropylene fibers (0.1% and 0.2%) were prepared and subjected to a series of mechanical tests, including compressive strength, tensile strength, and flexural strength. The results reveal that the optimal combination of bagasse ash and fibers significantly enhances the mechanical properties of concrete compared to conventional mixes. The inclusion of 20% bagasse ash with 1% steel fibers demonstrated the highest compressive strength, while the addition of polypropylene fibers contributed to improved ductility and crack resistance. These findings suggest that utilizing bagasse ash and fibers in concrete not only promotes sustainability but also improves performance characteristics, offering a viable alternative for high-performance concrete applications. This study highlights the potential of agricultural byproducts and synthetic fibers in creating more durable and eco-friendly concrete solutions.
