In this research, I tried to investigate the effect of polyurea coating on improving the impact resistance of concrete. As a synthetic high strength elastomeric coating material, polyurea performed well to protect concrete structures against different loads. Because of its chemical nature, polyurea also offers excellent chemical resistance and moisture protection. In this paper, the relationship between the efficacy of polyurea and impact strength is demonstrated. Additionally, various structure designs are tested during the experiment, including polyurea coated on the blast-receiving face, the back side face, and the interior face between concrete tiles to form a sandwich structure. Those samples were subjected to impact loads while conducting a drop tower experiment where the objective was to study the mechanism behind the improvement of impact resistance.
