non destructive testing of concrete

concrete compression testing machine

concrete hardness tester

1. Use a grinding stone to smoothen the test surface

 

2. Perform a few test impacts with the rebound hammer on this smooth, hard surface before taking any measurements which you are going to evaluate. Perform a consistency check on the test anvil

 

3.Ensure all settings are correctly done.

 

4 Position the hammer perpendicular to and against the test surface. Push the concrete test hammer adainst the surface at a moderate spped until the impact is triggered. Bes aware that the plunger generates a recoil when it deploys. Therefore it is recommentded to hold the rebound hammer with both hands, perpendicular to the test surface, before triggering the impact.

 

5. Each test surface should be tested with at least 12 impacts dropping the highest and the lowest and then take the average of the remaining. The individual impact points must be spaced at least 25mm apart. 

 

6 Interpret the test results.
