Description

Concrete Rebound Hammer is used for estimating the concrete strength and non destructive test on concrete. These are very durable and ensure error free performance for a long duration. These are manufactured using qualitative grades of MOC and are promised for on time performance.

 

Operation:

 

  • It consists of a barrel in which is housed a hammer mass attached to an impact spring which slides on a guide bar.
  • A plunger is attached to the guide bar which is pressed against the surface to be tested.
  • As the piston is pressed against the surface to be tested, on reaching the compressive strength, the hammer mass is released and rebounds to a certain extent (according to the strength of the surface) which is indicated by a rider on a calibrated scale.
  • A lock button fixed on the body of the hammer locks the rider in place and the rider can be recurred to zero position by using the same button.
  • The equivalent compressive strength can be computed from the chart supplied.
  • Each hammer is calibrated against at standard test hammer, and is suitable for specimen of compressive strengths 100 – 700 kg/cm.
  • The instrument, complete with a grinding stone for polishing the test surface, is supplied in carrying case.
