The concrete hammer is a resilience of a
momentary elastic deformation generated by a spring driven hammer and hitting the concrete surface by the impact rod, so that the
hammer bounces the pointer back and indicates the distance of the rebound.The rebound value (the ratio of the distance between the
rebound and the distance between the impact hammer and the impact rod before impact) is calculated as one of the indicators
related to the compressive strength of the concrete to estimate the compressive strength of the concrete. An instrument.
