Question 2.
Name one factor that can affect the shape of a deterioration curve.
Show hintHide hint
Consider the conditions concrete is exposed to.
3Question 3.
What do deterioration curves represent?
- Concrete's initial strength
- Performance degradation over time

Question 5.
Given a deterioration curve for a concrete cube exposed to high humidity, predict the time it will take for the compressive strength to drop below acceptable levels.
Show hintHide hint
Look for the slope and duration indicated on the curve.
Question 6.
Develop a maintenance strategy based on two different deterioration curves representing varying environmental conditions (dry vs. moist).
Show hintHide hint
Consider how each environment impacts the metrics plotted.
