Concrete rebound hammer

The concrete hammer is a resilience of a momentary elastic deformation generated by a spring-driven bombing and hitting the concrete surface by the impact rod, causing the hammer to bounce the pointer back and indicate the distance of the rebound. The rebound strength (the ratio of the bounce distance to the distance between the impact hammer and the impact bar before impact, calculated as a percentage) is one of the indicators related to the compressive strength of the concrete to estimate the compressive strength of the concrete.
