scope:
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 may 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 determination of concrete, but with suitable correlations it can provide an estimate of in situ strength.
