Non-Destructive 2.207j Testing Concrete Schmidt Rebound Hammer

2019-12-17concrete test hammer modeltype n schmidt hammer or rebound hammer test of concrete rebound hammer test is a non-destructive ndt test of concrete and simple concrete test which is used to test the compressive strength of concrete without any d...

Rebound hammer is also known as Schmidt’s Hammer or Swiss Hammer as it is invented by Ernst Schmidt, a Swiss engineer. 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 ...

Compressive strength is probably one the most crucial properties of concrete material. For existing structures, core samples are drilled and tested to obtain the concrete compressive strength. Many times, taking core samples is not feasible, and as a result, nondestructive methods to examine the concrete are required. The rebound hammer test is one of the most popular methods to estimate ...

INTRODUCTION: The meter is in accordance with technical regulation of JGJ/T23-2001, used for testing of concrete compressive strength within the scope of 1 0-60Mpa, with the system standard energy of 2.207J, and value indicating system of pointer direct reading.Our concrete resiliometer has been approved as “Recommended Product for Engineering Construction’’ B y the Ministry of construction.

After destructive test methods, the rebound number method is more efficient in predicting the strength of concrete under certain conditions. Schmidt Hammer rebound tests is recommended to estimate the strength of concrete to reduce the number of cores taken from the structures in practical cases.

Silver Schmidt Hammer use and Q values. The most common non destructive method for concrete compressive strength estimation is Schmidt hammer (rebound hammer) testing. Most often used is the Original Schmidt type N. This hammer has been around since the 1950s and is designed to be used on mass concrete over 100mm thick.

The correlation between concrete strengths and UPV determined by earlier researchers [9,10] were generally limited to the specimens prepared in laboratory conditions. Different correlation formulas were developed for different concrete mixture ratios. Amasaki S. [11] used rebound hammer method for the determination of strength of concrete ...
