11.13.2. Deterioration Curves

Try these first

1. 1.

   What are deterioration curves?

   Hint

   Think about functions that show trends in decline.

2. 2.

   Name one factor that can affect the shape of a deterioration curve.

   Hint

   Consider the conditions concrete is exposed to.

3. 3.

   What do deterioration curves represent?

   • Concrete's initial strength
   • Performance degradation over time
   • Curing methods

   Hint

   Focus on what the term 'deterioration' implies.

4. 4.

   Do deterioration curves help in maintenance planning?

   • True
   • False

   Hint

   Consider how predictions can aid in planning.

5. 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.

   Hint

   Look for the slope and duration indicated on the curve.

6. 6.

   Develop a maintenance strategy based on two different deterioration curves representing varying environmental conditions (dry vs. moist).

   Hint

   Consider how each environment impacts the metrics plotted.
