Concrete Test Hammer Rebound Hammer with Lab Calibration

Popular Non Destructive Testing of Concrete Structure

1. Rebound Hammer-RH (Schmidt) Test. In 1948, a Swiss Engineer, Ernst Schmidt from Zurich developed a test hammer for measuring the hardness of concrete by the rebound principle. Since then the Rebound Hammer (RH) test has gained recognition at construction site & precast Industry.

Rebound Hammer Test | Rebound Hammer Test Procedure

The procedure for rebound hammer test on hardened concrete starts with the calibration of the rebound hammer. 1) The rebound hammer is tested against the anvil made of steel having a Brinell hardness of about 5000 N/mm 2.. 2) After the rebound hammer is calibrated for accuracy on the test anvil, the rebound hammer is held at the right angle to the surface of the concrete structure for taking

How to do rebound hammer test to check compressive

The test hammer will hit the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete and is measured by the test equipment. By reference to the conversion chart, the rebound value can be used to determine the compressive strength.

Schmidt Concrete Test Hammer | CMTE Sales & Service

The Concrete Test Hammer is used to perform non-destructive strength tests of in place concrete. The hammer is designed to hit the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete. The rebound value, via reference tables, converts directly to the compressive strength of the concrete. Set includes hammer, rub stone, calibration curves and plastic
