How to Use a Manual Rebound Hammer:
1. Select Test Area:
Pick a clean, smooth, and dry concrete surface free of dust, paint, or loose particles.
2. Position the Hammer:
Hold the hammer firmly perpendicular to the surface.
3. Trigger the Impact:
Press the plunger until the spring releases and strikes the concrete.
4. Read the Rebound Value:
Note the reading shown on the scale immediately.
5. Take Multiple Readings:
Perform 8–10 tests in the area, discard outliers, and calculate the average.
6. Interpret the Results:
Compare the average rebound number with the manufacturer’s conversion chart to estimate concrete compressive strength.
7. Document findings.
