This study aimed to evaluate the feasibility and usefulness of using the signal created by the impact force after the first impact of an object and subsequent impact of rebounds to evaluate the concrete’s compressive strength non-destructively. Three distinct materials (steel, concrete, and wood) were tested to compare the compressive strengths and signal response using a developed device. The test results demonstrated that the compressive strength of different materials could be effectively represented using the impact force response signals. Following the test results, field case studies were conducted on three different structures. The studies also showed a direct correlation between the impact force response signal and the compressive strength of concrete. Based on the study findings, the total impact force signal energy, which was determined by integrating the impact force response signal, could be used to non-destructively evaluate the compressive strength of concrete materials.
