concrete strength through fibre reinforcement, synthesizing insights from five prominent research papers. The focus centers on the impact of various fibres, such as steel, polypropylene, and glass, on concrete properties like strength, durability, and crack resistance. In conjunction with the literature review, a practical experiment was conducted involving the controlled breaking of 150x150x150mm concrete cubes And 700x150x150mm Beam. The broken cubes were then meticulously repaired using Fibre Reinforced Concrete (FRC) to assess the effectiveness of FRC in improving strength. Preliminary results indicate a substantial increase in compressive strength and enhanced resistance to cracking in the repaired cubes compared to the control group. These findings align with trends observed in the literature, highlighting the positive influence of fibre reinforcement on concrete performance. The research contributes valuable insights, with the practical experiment emphasizing the applicability of FRC for repairing and strengthening concrete structures.
These findings not only corroborate trends observed in the literature but also underscore the transformative potential of FRC in reinforcing and repairing concrete structures. By bridging theoretical insights with practical application, this research contributes valuable knowledge to the field, emphasizing the practical viability and effectiveness of FRC as a sustainable solution for enhancing concrete performance.

1.INTRODUCTION In recent years, the enhancement of concrete properties through fibre reinforcement has garnered significant attention in civil engineering research. This study delves into the realm of fibre-reinforced concrete (FRC), focusing on its profound impact on the strength, durability, and crack resistance of concrete structures. By synthesizing findings from prominent research papers, this investigation explores the effects of various fibres, including steel, polypropylene, and glass, on concrete performance. Central to this research is a practical experiment designed to assess the efficacy of FRC in enhancing concrete strength. The experiment involved controlled breakage and subsequent repair of 150x150x150mm concrete cubes and 700x150x150mm beams using Fibre Reinforced Concrete (FRC). Initial results from the experiment reveal promising outcomes, indicating a notable increase in compressive
