Question 1
What is creep in concrete?
- A short-term deformation
- A gradual increase in strain
- A type of crack
💡 Hint: Remember what happens to concrete when a constant load is applied over a long period.
Question 2
True or False: Shrinkage does not affect the structural integrity of concrete.
- True
- False
💡 Hint: Think about the consequences of material changes over time.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a newly erected 20-meter beam. If excessive creep causes a projected deflection exceeding 35mm by the end of its service life, what actions should a civil engineer propose to mitigate this risk?
💡 Hint: Think about both material properties and structural design.
Question 2
Evaluate how the use of supplementary cementitious materials might influence shrinkage rates in a large concrete pour and its consequent cracking patterns.
💡 Hint: Consider the properties of the materials used.
