Question 1.
What is creep in concrete?
Show hintHide hint
Think about how materials behave under constant pressure.
Question 2.
Define shrinkage.
Show hintHide hint
Consider what happens to concrete as it dries.
3Question 3.
What is the main effect of creep on prestressed concrete?
- A) Increases cracking
- B) Reduces strength
- C) Leads to prestress loss
Show hintHide hint
Think about how stress changes over time.
4Question 4.
True or False: High-Performance Concrete generally has a higher water-cement ratio.
- True
- False
Show hintHide hint
Remember the relationship between strength and water-cement ratio.
Question 5.
Evaluate the effects of different water-cement ratios on both creep and shrinkage in High-Performance Concrete. How would these factors impact structural design?
Show hintHide hint
Reflect on how strength correlates with the water mixture's amount.
Question 6.
Analyze a mass concrete structure affected by thermal stresses. What design adjustments could be recommended to minimize thermal shrinkage effects?
Show hintHide hint
Consider how temperature changes during hydration affect the structure.
