Concrete Test Hammer

A Schmidt hammer, also known as a Swiss hammer or a rebound hammer or concrete hammer test, is a device to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance. It was invented by Ernst Heinrich Wilhelm Schmidt, a Swiss engineer.The Concrete Test Hammer is a measuring tool for testing the strength of concrete. The Concrete Test Hammer measures strength according to the Schmidt principle. According to this measurement method, the quality of concrete can be measured with the Concrete Test Hammer.A non-destructive technique used to determine the compressive strength, surface hardness and penetration resistance of reinforced concrete and masonry structures by measuring the rebound of a spring-loaded mass impacting against the surface of the sample. The hammer hits the surface at a defined energy.
