2.2. Passing Ability

Try these first

1. 1.

   Define Passing Ability in the context of SCC.

   Hint

   Think about how concrete behaves around obstacles.

2. 2.

   What is the purpose of measuring Passing Ability?

   Hint

   Consider the structure's integrity.

3. 3.

   What is the main purpose of Passing Ability?

   • To ensure good flow
   • To measure compressive strength
   • To enhance aggregate size

   Hint

   Think about how concrete fills a form.

4. 4.

   True or False: The L-Box test measures the segregation resistance of SCC.

   • True
   • False

   Hint

   Consider what each test is designed for.

5. 5.

   Evaluate a construction project that used SCC without conducting an L-Box test. Discuss potential risks and suggest remedial measures.

   Hint

   Think about the implications of not testing before placement.

6. 6.

   Design a scenario where the Passing Ability of SCC improves overall construction efficiency. Include specific applications and test methods.

   Hint

   Consider how the characteristics of SCC can lead to time savings.
