There is no actual reading in the rebound hammer , Actually rebound hammer test results are + - 15 to 30 % fluctuate, So core test better than rebound hammer , And the strength of the core actually comes , Whereas the result of the rebound hammer test does not come actual.. So finally core cutter test better than rebound hammer test..
