Schmidt Hammer

• Rebound hammer test is done to find out the
  compressive strength of concrete by using rebound
  hammer as per IS 13311 (Part 2) - 1992. The
  underlying principle of the rebound hammer test
  is The rebound of an elastic mass depends on
  the hardness of the surface against which its
  mass strikes.
• A simple equipment known as Rebound Hammer or
  Schmidt Hammer is used for this purpose. The
  Schmidt rebound hammer is principally a surface
  hardness tester. The Original Schmidt is
  available in models with different impact
  energies, each test hammer designed for a
  specific test application.
• The test hammer will hit the concrete at a
  defined energy. Its rebound is dependent on the
  hardness of the concrete and is measured by the
  test equipment.
