Rebound Hammer Test (Schmidt hammer) Useful for non-destructive estimation of quality of concrete of a finished structure and its relative compressive strength. The instrument consists of a casing in which a hammer mass, special spring, hammer locking and release mechanism are housed. A spherical ended plunger projects at one end which, when pressed against the test surface, actuates the release mechanism of the hammer mass. It gives an impact on the plunger. The hammer mass rebounds after the impact and an indicator register the amount of rebound on a linear scale. The compressive strength of the material can be computed from the calibration curves supplied with each hammer. It gives results within 15% of actual compressive strength.
