3.9. Combined Use of NDT Techniques

Try these first

1. 1.

   What is the main purpose of combining NDT techniques?

   Hint

   Think about the objective of using more than one testing method.

2. 2.

   Name one NDT technique used for surface testing.

   Hint

   This test measures the hardness of the surface of concrete.

3. 3.

   What does combined use of NDT techniques help improve?

   • Cost efficiency
   • Reliability of results
   • Speed of tests

   Hint

   Think about the main goal behind using more than one method.

4. 4.

   True or False: Core Cutting is completely non-destructive.

   • True
   • False

   Hint

   Think about the impact on the structure when performing this test.

5. 5.

   Design a testing plan for a concrete structure showing signs of distress. Include the order of NDT techniques you would use and justify your choices.

   Hint

   Consider how to minimize damage to the structure while maximizing information gained.

6. 6.

   Analyze a situation where environmental conditions might affect NDT results. What steps can you take to mitigate these effects?

   Hint

   Think about how moisture or temperature changes can impact your test readings.
