This brick rebound tester uses a spring driven hammer to measure the instantaneous elastic shape generated by the hammer hitting the surface of the brick sample through the hammer rod
Change the restoring force to make the hammer drive the pointer to bounce back and indicate the rebound distance, using the rebound value as the relevant indicator of the compressive strength of the brick
1、 To estimate the compressive strength and grade of bricks. It is used for non-destructive testing of the strength of sintered ordinary bricks and is also suitable for detecting light bones
The strength of concrete and other lightweight materials.
characteristic:
Lightweight, flexible, inexpensive, no need for power, easy to control, very suitable for on-site construction sites and small and medium-sized brick factories.
Main technical parameters:
Nominal kinetic energy 0.735J
The impact length of the hammer is 75 ± 0.3mm Friction force of pointer slider 0.5 ± 0.1N The working length of the rebound spring is 61.5 ± 0.3mm The "100" mark on the scale of the detachment position of the impact hammer The spherical radius at the end of the firing rod is 25 ± 1mm Steel anvil set value 74 ± 2 |
