How do you know the compressive strength of a rebound hammer?

Sigma Test13 Oct, 2021Business

A rebound hammer is an instrument used to measure the strength, resistance, or elastic properties of concrete. The rebound hammer is a non-destructive testing instrument, where the rebound of the spring-driven stack is measured with the concrete surface after its impact on it. The result of the rebound hammer is mentioned as a rebound number and also correlates with the hardness of the surface of the concrete.
