rebound hammer test procedure

Rebound Hammer Test procedure for Concrete Hardness- rebound hammer test procedure ,2/3/2017· Rebound Hammer Test Procedure: 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.Rebound hammer - ConcreteThe rebound hammer should be considered as a means of determining variations of strength within a structure rather than an accurate means of assessing strength. The surface under test should be clean and smooth. Dirt or other loose material on the surface

Rebound Hammer (Schmidt Hammer) - GBG

Procedure. The surface of the concrete is cleaned to remove laitance and shutter board marks. A series of twelve readings are taken with a 'Schmidt' hammer in a diamond pattern at the test point. The hammer is pressed against the surface, loading the sprung mass, and releasing this at the end of the stroke. The percentage rebound is measured by ...

REBOUND HAMMER TEST - Concrete Civil Engineering

21/4/2018· INTRODUCTION The rebound hammer test is one of the non-destructive tests used to check the compressive strength of concrete. The rebound hammer is designed to carryout instant nondestructive test on concrete structure without damage and gives an immediate indication of the compressive strength of the concrete using the calibration curve applied each instrument.
