Rebound Hammer Test
Rebound hammer test is done to find out the compressive strength of concrete by using rebound hammer as per IS: 13311 (Part 2) – 1992. The underlying principle of the rebound hammer test is: The rebound of an elastic mass depends on the hardness of the surface against which its mass strikes.

BS EN 12504-2:2001
This European Standard, a part of the BS EN 12504 series, specifies a method for determining the rebound number of an area of hardened concrete using a spring driven steel hammer. The rebound number determined by this method can be used to assess the uniformity of concrete in situ, to delineate zones or areas of poor quality or deteriorated concrete in structures.
Schmidt hammer
The hammer measures the rebound of a spring-loaded mass impacting against the surface of a sample. The test hammer hits the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete and is measured by the test equipment. By reference to a conversion chart, the rebound value can be used to determine the concrete’s
Concrete Test Hammers
Testing Anvils Each test hammer should be checked after 1,000 test impacts. A testing anvil is used to check whether the rebound test mechanism is working correctly. In case of values beyond the tolerance (due to contamination by very fine cement, wear or
