The rebound hammer test is used to determine the compressive strength of concrete. The test hammer hits the concrete at a defined energy, and its rebound is dependent on the hardness of the concrete and is measured by the test equipment1. By reference to a conversion chart, the rebound value can be used to determine the concrete's compressive strength1. The result of the rebound hammer test is obtained by plotting a graph using the values obtained from the rebound hammer number and the compressive strength of the concrete2. The accuracy of the result may differ by ±25% to the compressive strength of the concrete2.Learn more:✕This summary was generated using AI based on multiple online sources.
