The growing concern over the environmental impact of cement production, which contributes significantly to CO₂ emissions, has prompted the exploration of alternative materials to partially replace cement in concrete. This experimental investigation evaluates the effects of replacing cement with Recron fiber (synthetic polymer fiber) and wooden fiber (natural fiber) on the mechanical and durability properties of concrete. Concrete mixes were prepared by partially replacing cement with 1%, 0.75% and 5%,10% by weight of Recron and wooden fibers, respectively. The key properties assessed include compressive strength, flexural strength, split tensile strength, workability. The results indicated that the incorporation of both Recron and wooden fibers improved the mechanical properties of concrete up to a 2% replacement level. Recron fiber exhibited a more pronounced enhancement in compressive, flexural, and split tensile strengths compared to wooden fiber. Beyond 2% replacement, a decline in strength was observed, likely due to a reduction in the effective cement content and the tendency of fibers to cluster. Additionally, both types of fibers contributed to improved durability, as evidenced by reduced water absorption
