Rebound Hammer Test procedure for Concrete Hardness

Mar 02, 2017  In the procedure of rebound hammer test, the plunger of rebound hammer is pressed on the surface of concrete, so that a spring controlled mass with a constant energy is made to hit the concrete surface. At the same time, a spring controlled mass rebounds back. This extent of rebound on a graduated scale is measured for the surface hardness.
