Testing Concrete in Structures - Part 2: Non-Destructive Testing - Determination of Rebound Number
Also Known As:
The DIN EN 12504-2 standard is a method used to determine the rebound number of hardened concrete using a spring-driven hammer. The rebound number is a measure of the hardness of the concrete and can be used to assess the uniformity of concrete in structures and identify areas of poor quality or deteriorated concrete.
It is important to note that this test method is not intended as a replacement for the compressive strength determination of concrete. However, with suitable correlation, the rebound number can provide an estimate of the in situ compressive strength. For a more accurate assessment of in-situ compressive strength, the EN 13791 standard should be used.
The spring-driven hammer can also be used for comparative testing, where the rebound number is referenced against a concrete with a known strength or against a concrete that has been tested and verified as conforming to a particular strength class.
