The rebound hammer can provide an estimate of compressive strength of the concrete according to IS: 13311 (Part 2). It is a non-destructive testing device, which is used on finished concrete structures, such as precast concrete septic tanks. We offer a complete line of Rebound Hammers for the occasional user as well as the engineering professional. All hammers are spring activated and conform to ASTM C-805 as well as other European and Asian Standards. All are made to the most exacting machine tolerances to provide the end user with a consistent test every time. A Schmidt Hammer or a rebound hammer is a device to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance. Hammer test.
