Concrete Test Hammer (Rebound Hammer ))

Model: ASI-631 & ASI-632

The concrete test hammer is an instrument which is easy to use, for quick and approximate measurement of the resistance to pressure of manufactured concrete products.

The principles on which it works are based on the rebound impact of a hammer on a piston which rest against the surface of the concrete products.

The Greater the resistance on the concrete, greater is the rebounded impact.

By reading this rebound impact on a scale and relating it to curves on graphs supplied with the instrument, the resistance to compression in MPa or PSI can be found, with +/-20 % of actual.

Specifications:

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 a 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 richard 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

Detailed Description

Concrete Test Hammer (Big)

Model: ASI-632
It is similar to the above but is used for testing concrete with over size aggregates (for which test, cubes promise no reliable results) and for testing concrete roads.

Its plunger is wider as such, the amount of concrete reached by the impact is considerably greater.

With this model also the results obtained are within +/-20% of the actual compressive strength.

The instrument is supplied with two handles which can be attached to the body of the concrete test hammer for carrying out the test easily. Complete with grinding stones.
