IS 516 : Part 5 : Sec 4 : 2020 Hardened Concrete-Methods of Test - Part 5 Non-Destructive Testing of Concrete - Section 4 Rebound Hammer Test
New Standard from Last Update.
1 SCOPE
This standard (Part 5/Sec 4) covers the objective, principle, apparatus and procedure of rebound hammer test for determination of the rebound number of hardened concrete using a spring-driven steel hammer. In addition, influence of test conditions and some general guidance on the interpretation of test results are also given.
NOTE — The test method is not intended as an alternative for the compressive strength determination of concrete; but with suitable correlation, it can provide an estimate of in-situ strength.
