concrete test hammer

The concrete test hammer uses the spring to drive the hammer, which produces the restoring force of the instantaneous elastic deformation on the concrete surface by the rod. The hammer drives the pointer to rebound and indicates the rebound distance rebound value. It is widely used in construction, municipal engineering and road and bridge construction process of concrete compressive strength testing. Using it to test the compressive strength of concrete is the most widely used nondestructive testing instrument for concrete compressive strength. This is the fastest, simplest and most economical test method for obtaining concrete quality and strength
