3.12. Emerging Trends in NDT of Concrete

Try these first

1. 1.

   What does GPR stand for?

   Hint

   Think about radar and ground in the context of NDT.

2. 2.

   Name one use of infrared thermography.

   Hint

   Consider temperature differences.

3. 3.

   What does GPR primarily detect?

   • Temperature differences
   • Subsurface features
   • Surface cracks

   Hint

   Think about what's beneath the surface.

4. 4.

   True or False: Infrared Thermography can only detect surface-level issues.

   • True
   • False

   Hint

   Consider what thermal imaging can reveal.

5. 5.

   A heritage structure shows signs of instability after heavy rainfall. Propose an NDT strategy using at least two methods.

   Hint

   Consider both internal and external sources of potential issues.

6. 6.

   After conducting GPR, you discovered several voids beneath a concrete slab. Describe the implications for the structural integrity and recommend follow-up actions.

   Hint

   Think about how the findings from GPR can change your next steps.
