Extensive research is being conducted globally on incorporating fibres into concrete to enhance its mechanical properties. This study aims to evaluate the strength characteristics of fibre-reinforced concrete (FRC) with varying mix proportions. 18 concrete samples of M-25 grade were prepared, incorporating different percentages of steel and glass fibers. Six samples contained glass fibres (GF) at 5%, 10%, and 15% by weight of cement, and six contained steel fibres (SF) at the same percentages. Additionally, two samples were prepared with a combination of 5% glass fibres and 10% steel fibres and two samples with 10% glass fibres and 5% steel fibres. These were compared to a control sample without fibre reinforcement. The compressive strength of the FRC was assessed at 7 and 28 days. The findings indicate that higher percentages of glass fibers had a notably negative impact on compressive strength, while the inclusion of steel fibers had a comparatively lesser effect. The maximum compressive strength was observed by including 5% steel fibres at 28 days. However, increasing the fiber content beyond this percentage resulted in a reduction in compressive strength. The lowest compressive strength was recorded in samples containing 15% glass fibers at 28 days.
