Information Schmidt Rebound Hammers
Testing of the compressive strength of concrete in completed concrete structures.
Also used to monitor strength development, for example in connection with the setting time of concrete.
We supply several different models for determining the early strength of concrete and its strength development.
Rebound hammers can also be supplied for testing rock and stone materials:
Rock Schmidt RS8000 models N and L.
Models Type N: Standard impact energy, 2.207 Nm. Recommended for field work. For core testing ISRM* recommends that cores should be at least moderate strength (> 80 MPa) and at least T2 size (≥ 84 mm).
Type L: Low impact energy, 0.735 Nm. Recommended impact energy in the ASTM D 5873 standard for testing of cores. ISRM* recommends for testing on cores of moderate strength and above of at least NX size (≥ 54 mm).
Standards:
EN 13791 – Assessment of compressive strength in completed concrete structures and precast concrete elements.
EN 12504 – Testing of concrete in structures
