Rebound hammer graph. The Graph Contains Three different curves for three Different positions of Testing. Pos. A – Horizontal Position, Pos. B- Vertical down wards, Pos. C – Vertical Upwards, Step 4: Interpretation of Results. The result from the test tells us the quality of Concrete or rocks. Standards for Rebound Test Hammer: BS EN 12504
Rebound hammer test is done to find out the compressive strength of concrete by using rebound hammer as per IS: 13311 (Part 2) – 1992. The underlying principle of the rebound hammer test is. The rebound of an elastic mass depends on the hardness of the surface against which its mass strikes. When the plunger of the rebound hammer is pressed ...
NOTE - The rebound hammer method can be used with greater confidence for differentiating between the questionable and acceptable parts of a structure or for relative comparison between two different structures. 3.2 Principle of Test 5.1 It is necessary that the rebound hammer is
The rebound hammer is an inexpensive and quick method for nondestructive testing of concrete. The method should not be regarded as a substitute for core compressive testing but rather as a method for determining the uniformity of concrete in the structures and helping reduce the number of core samples.
Rebound hammers for geological and geotechnical applications test the strength and consistency of rock formations. These unique models evaluate age, weathering, and strength in rock formations or estimate penetration rates for tunnel boring machines. Whether you select a simple or advanced model, the concrete test hammer is versatile, reliable ...
