Detail Hammer Test NJ-80
Hammer Test NJ80
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.
