12.5. Challenges of SCC in Fresh State

Try these first

1. 1.

   What is the primary challenge related to the cost of SCC?

   Hint

   Think about the materials used in the concrete.

2. 2.

   How does a poorly designed mix affect SCC?

   Hint

   What happens when the ingredients are not properly balanced?

3. 3.

   What is a significant challenge of using SCC?

   • A) Low durability
   • B) High material costs
   • C) Easy mix design

   Hint

   Consider the expenses involved with SCC compared to traditional concrete.

4. 4.

   True or False: SCC does not require any quality control measures because it flows well.

   • True
   • False

   Hint

   Reflect on the importance of testing in construction.

5. 5.

   Discuss the trade-offs when choosing SCC over conventional concrete in a large-scale infrastructure project.

   Hint

   Consider factors like budget constraints, project timelines, and durability requirements.

6. 6.

   Evaluate how changes in environmental conditions (like humidity) can impact the performance of SCC.

   Hint

   Think about how weather affects materials in construction.
