Rebound test 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.
This NDT test method is not intended as an alternative for the compressive strength determination of concrete, but with suitable correlations already saved in the instrument, it can provide an estimate of in situ compressive strength.
The hammer may be used for comparative testing, referenced against a concrete with known strength or against a concrete verified as conforming to a particular strength class. Calibration Anvil, manufactured from a special steel alloy, is used for the calibration of concrete test hammers (Call to get more information).

Device meets requirements of the following standard:

  • PN-EN 12504 Testing concrete in structures. Non-destructive testing. Determination of rebound number
  • ASTM C805 Standard Test Method for Rebound Number of Hardened Concrete
