When testing the strength of concrete, the concrete test hammer uses a certain
elastic force to transit the impact force of an impact hammer to the surface
of concrete, its initial kinetic energy redistributes, a part of energy in the
form of
plastic deformation or residual deformation is adsorbed by the concrete, and
another part of energy which is proportional to the surface hardness is
transmitted to the impact hammer, making the hammer resile to a certain
height, then the strength of the concrete is derived from the proportional
relation between the height of resilience and the concrete strength.
With the merits of simple structure, easy correction, maintenance and repair,
and portability, the concrete test hammer is widely used in civil engineering
and construction industry for testing the strength of concrete. Compared to
other nondestructive testers, the concrete test hammer is an economical and
practical nondestructive testing instrument.
- HT-225A is used for testing the strength of various concrete members (slab, beam, column, truss) of normal building strength and bridge.
- HT-75 is used for testing small and impact-sensitive parts of concrete or artificial brick.
- HT-20 is used for testing mortar or clay of products.
