How to Use a Manual Rebound Hammer:
1. Prepare the Surface:
Ensure the concrete surface is clean, smooth, and dry. Remove dust, loose particles, or coatings.
2. Position the Hammer:
Hold the rebound hammer firmly and perpendicular to the concrete surface.
3. Press the Plunger:
Push the hammer until the spring-loaded plunger releases and strikes the concrete.
4. Read the Rebound Value:
Observe the reading on the scale immediately. This indicates the surface hardness.
5. Repeat the Test:
Take multiple readings (usually 10) on the same area to improve accuracy. Discard unusually high or low values and calculate the average.
6. Estimate Concrete Strength:
Use the rebound number and the manufacturer’s conversion chart to estimate compressive strength.
7. Record Data
