Repairing and rehabilitating structures is a significant aspect of construction activities, and reinforced concrete is a widely used material worldwide. Nevertheless, structures constructed with reinforced concrete often undergo various forms of damage, including overloading, natural disasters such as earthquakes and floods, fire incidents, environmental impacts such as corrosion, and alterations in building functionality, before reaching their intended design lifespan. These damages can lead to structural elements failing to meet functional requirements within their designated service life. It was applied to strengthening to ensure the member could safely support its intended load. This study investigates the effect of various thicknesses of reinforced concrete jacketing on flexural strength resistance. Reinforced concrete jacketing is a widely used technique for structural rehabilitation and strengthening that involves applying additional layers of concrete to existing structures. The study investigates various jacketing thicknesses and their impact on the structure's flexural strength. In this study, the increase in load carrying capacity is between 1.5 and 3 times greater than the original samples. This difference is caused by differences in the material, the steel reinforcement, and the thickness of the jacketing. Reinforced concrete jacketing can increase stiffness by up to 173%.
