Applications

The rebound hammer is a widely used non-destructive testing tool for assessing the strength and consistency of concrete structures. It is commonly used in construction and civil engineering applications to evaluate the compressive strength of concrete in areas such as bridges, dams, buildings, and pavements.

Tips: How to calibrate the rebound hammer？

A rebound hammer is a device used to measure the hardness or strength of concrete by measuring the rebound of a spring-loaded hammer. Calibration of the rebound hammer is important to ensure accurate and consistent results.

Here are the steps to calibrate a rebound hammer:

1. Choose a suitable test surface: Select a smooth, flat, and uniform surface for testing. The surface should be clean and free from any loose material, oil, or dirt.
2. Check the calibration anvil: Make sure the calibration anvil is in good condition and clean. The calibration anvil is a steel block with a known hardness that is used as a reference for calibration.
3. Place the rebound hammer on the anvil: Place the rebound hammer on the calibration anvil and push the button to release the hammer.
4. Take the reading: Note the reading displayed on the scale of the rebound hammer.
5. Repeat the process: Repeat the process of placing the hammer on the calibration anvil and taking the reading at least three times to get an average value.
6. Compare the readings: Compare the average reading obtained with the known value of the calibration anvil. The difference between the two values should be within ± 0.5 N/mm².
7. Adjust if necessary: If the difference between the two values is more than ± 0.5 N/mm², adjust the rebound hammer using the adjustment screw until the readings match.
8. Document the calibration: Document the calibration in a logbook or calibration certificate, including the date, name of the operator, and the results obtained.
