How to Use a Rebound Hammer:
1.Prepare the Surface:
Choose a smooth, clean, and dry area of concrete. Remove loose particles, dust, or coatings that could affect results.
2. Hold the Hammer Properly:
Position the rebound hammer firmly against the concrete surface, keeping it perpendicular to the test area.
3. Press the Plunger:
Push the hammer slowly until the spring-loaded plunger releases and strikes the concrete.
4. Read the Rebound Value:
Note the rebound number shown on the scale. This value indicates surface hardness.
5. Repeat the Test:
Take at least 10 readings in the same area and discard unusually high or low values. Calculate the average.
6. Interpret Results:
Compare the average rebound number to the manufacturer’s conversion chart to estimate concrete compressive strength.
