Testing concrete in structures - Non-destructive testing. Determination of rebound numberThis 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. The test method is not intended as an alternative for the compressive strength
