Description:
- Concrete rebound hammer (sclerometer) – is a device for concrete and other building materials strength testing. The engineer Ernst Schmidt invented the construction of the sclerometer.
- The method is based on the impacting the impact plunger on the concrete surface with predetermined (normed) impacting energy and subsequent measuring of the height of the striker rebounding. The height of the striker rebounding will be proportional to the strength of concrete. The strength of concrete is determined with the calibration charts that are supplied with the instrument.
- Concrete Rebound Hammer NOVOTEST SH is very ease in operation, has good reliability of design and high measurement accuracy, so that this method is the most common method of measuring the strength of concrete in the world. The strength testing with the Concrete rebound hammer is correspond with ASTM C 805; ASTM D 5873 (for rock); DIN 1048, p. 2; ENV 206; EN 12 504-2; ISO / DIS 8045.
