Non-Destructive Testing
Schmidt Rebound Hammer
Concrete test hammer for non-destructive assessment of surface hardness and uniformity of hardened concrete, supplied with abrasive stone.
Overview
The Schmidt Rebound Hammer assesses the surface hardness and uniformity of hardened concrete in a fast, non-destructive test. The spring-loaded hammer is pressed against the concrete surface and the rebound distance, read from the graduated scale on the calibration chart, gives a rebound index that correlates to compressive strength. The supplied abrasive stone is used to prepare a smooth test surface before each reading. Ideal for checking uniformity across structures and identifying areas for further testing.
