12. Durability Testing in Real-Time Projects

Try these first

1. 1.

   What is core sampling used for?

   Hint

   Think about what properties we need to evaluate in concrete.

2. 2.

   Name one non-destructive testing technique.

   Hint

   This test gives a measure of surface hardness.

3. 3.

   What does core sampling assess in concrete?

   • Only compressive strength
   • Carbonation depth and chloride content
   • Both compressive strength and water absorption

   Hint

   Think about what properties we measure from the concrete cores.

4. 4.

   True or False: Non-Destructive Testing causes damage to the structure being evaluated.

   • True
   • False

   Hint

   Focus on the meaning of 'non-destructive.'

5. 5.

   A concrete structure shows visible signs of cracking and spalling. Discuss a systematic approach using both core sampling and NDT to assess its condition.

   Hint

   Combine methods to evaluate both internal and external factors.

6. 6.

   A contractor is planning to use a rebound hammer test on a new concrete pour. Discuss potential limitations of this method and recommend complementary tests.

   Hint

   Consider what rebound hammer can't assess.
