Testing Concrete in Structures - Part 2: Non-Destructive Testing - Determination of Rebound Number
Also Known As:
The DIN EN 12504-2 standard provides a method for determining the rebound number of hardened concrete using a spring-driven hammer. The rebound number obtained from this test can be used to assess the uniformity of concrete within a structure and identify areas with poor quality or deteriorated concrete.
It is important to note that this test method is not meant to replace the determination of compressive strength of concrete. However, with suitable correlation, the rebound number can give an estimate of the in situ compressive strength. For a comprehensive assessment of in-situ compressive strength, reference should be made to EN 13791.
The hammer used in this test can be used for comparative testing, where it is compared to a concrete sample with known strength or a concrete sample from a defined volume that has been verified to conform to a particular strength class. This allows for relative comparisons and assessment of the quality and strength of the tested concrete.
