Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the primary measurement of yield stress in SCC?
- Minimum stress to initiate flow
- Maximum material strength
- Compression resistance
💡 Hint: It's the initial force that SCC needs to overcome.
Question 2
Is thixotropy essential for SCC stabilization?
- True
- False
💡 Hint: Think about how SCC behaves after being placed.

Challenge Problems
Push your limits with challenges.
Question 1
Imagine you are designing an SCC mix with low yield stress, but you also want to ensure it maintains sufficient viscosity. How would you balance the two, and what components would you adjust?
💡 Hint: Think about how changing components affects both properties.
Question 2
If an SCC application requires optimal thixotropic behavior to hold its shape in a vertical structure, explain how you would achieve this through mix design and what testing you would conduct.
💡 Hint: Consider how different elements in the mix can affect stability.
