As per the Indian code IS: 13311(2)-1992, the rebound hammer test have the following objectives:
- To determine the compressive strength of the concrete by relating the rebound index and the compressive strength
- To assess the uniformity of the concrete
- To assess the quality of the concrete based on the standard specifications
- To relate one concrete element with other in terms of quality
Rebound hammer test method can be used to differentiate the acceptable and questionable parts of the structure or to compare two different structures based on strength.
