3.4. Guidelines

Try these first

1. 1.

   What is the purpose of core cutting in concrete testing?

   Hint

   Think about why we can't rely solely on NDT results.

2. 2.

   Name one apparatus used in core cutting.

   Hint

   It's a machine specifically designed for this task.

3. 3.

   What is the primary goal of core cutting?

   • To evaluate surface strength
   • To extract concrete samples
   • To assess environmental impact

   Hint

   Consider the methods we've discussed for assessing concrete.

4. 4.

   True or False: Core cutting is a non-destructive testing method.

   • True
   • False

   Hint

   Recall the differences between NDT and semi-destructive methods.

5. 5.

   You are assessing a building with uneven settling. Explain how you would utilize core cutting and NDT methods to evaluate the structure and ensure safety.

   Hint

   Think about the order of operations based on the reliability of results.

6. 6.

   A core sample reveals a strength of 18 MPa, but the specification is 25 MPa. What steps do you recommend for the building's structural integrity?

   Hint

   What actions can you take based on the severity of the situation?
