T-BOTA HT-20 low strength structures point type mortar rebound hammer concrete test hammer

HT-20 point  concrete test hammer

hen 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
