Concrete containing high honeycombs and no-fines concrete is not suitable to be tested by a rebound hammer. The strength is overestimated by the test when testing floated or troweled surfaces when compared with molded surfaces.Rebound Hammer Test | Rebound Hammer Test Procedure - CiviconceptsWhat is rebound hammer method?The rebound hammer method provides a convenient and rapid indication of the compressive strength of concrete by means of establishing a suitable correlation between the rebound index and the compressive strength of concrete. The procedure of obtaining such correlation is given in 4.2.REBOUND HAMMER TESTWhat is a rebound hammer test?The rebound hammer test isnot intended as a substitute for standard compression test, but as a method for determining the u iformity ofconcrete in the structure and comparing one concrete with another.
