The rebound method is the most commonly used and convenient non-destructive method for on-site testing of concrete compressive strength.
However, different personnel often have differences in the testing results of the same component, which is often not a problem with the instrument, but rather due to differences in understanding and operational details of the “Technical Specification for Testing Concrete Compressive Strength by Rebound Method” (JGJ/T 23-2011).
The key to mastering the essence of this regulation lies in understanding “why” rather than just “what to do”.
