Concrete Test Hammer

Product Description

Concrete Test Hammer: MTCT-110

Concrete structures will need to be examined and tested to ensure the concrete remains of adequate strength and durability. Rebound hammer surveys can be conducted to provide a rough estimate of concrete strength, where it is not possible to determine this by more accurate means such as core extraction and testing. The test involves using a special rebound hammer, which measures the recoil of a piston against the concrete surface when a standard force is applied. This recoil can then be correlated approximately to concrete strength.

SPECIFICATION

• The rebound hammer 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 lock the rider in place and the rider can be reset to zero Position by using the same button.
• The equivalent compressive strength can be computed from the chart supplied.
• It is suitable for specimen of compressive strengths 100-700Kg/cm.
• The instrument, complete with a grinding stone for polishing the test surface.
