        abstract = {The pursuit of sustainable construction materials has spurred innovative research into enhancing the structural performance of concrete while reducing its environmental impact. This study focuses on the development of sustainable concrete by incorporating hybrid fibres and silica fume, aiming to improve its mechanical properties. The investigation includes a comprehensive assessment of the material's performance through compressive, split tensile, and flexural strength tests at curing periods of 7, 14, and 28 days. Silica fume, a byproduct of the silicon and ferrosilicon alloy industries, presents an opportunity to enhance concrete properties. In this research, varying replacement percentages of cement with silica fume (5%, 10%, 15%, 20%, and 25% by weight) were considered. This addition aims to enhance the concrete's strength and durability by reducing the porosity and increasing the density of the matrix. Furthermore, the study incorporates hybrid fibres into the concrete mix. These fibres, a combination of steel and polypropylene, were added at a replacement percentage of 2% by volume of the coarse aggregate. Hybrid fibres offer a balanced enhancement of both tensile and flexural properties, promoting crack control and ductility, especially in challenging structural conditions. The experimental program involves the preparation of concrete specimens with varying proportions of silica fume and hybrid fibres, alongside a reference mix for comparison. Compressive strength tests assess the load-bearing capacity, while split tensile strength tests evaluate the concrete's resistance to cracking. Flexural strength tests provide insights into the material's bending behaviour, crucial for applications subject to dynamic loads. The results demonstrate promising trends. The inclusion of silica fume led to improved compressive, split tensile, and flexural strengths.},
