Try these first

1. 1.

   What is durability-based failure in concrete?

   Hint

   Think about environmental conditions affecting concrete.

2. 2.

   Name one cause of corrosion in reinforced concrete.

   Hint

   What material could contribute to rusting?

3. 3.

   What is a primary cause of durability-based failure in concrete?

   • High temperature
   • Corrosion
   • Poor mix design

   Hint

   Consider chemical reactions that can harm steel.

4. 4.

   Freeze-thaw action can lead to what type of concrete damage?

   • True
   • False

   Hint

   Think about the effects of temperature changes on liquids.

5. 5.

   Explain how the design of a bridge in a cold climate should consider freeze-thaw action to ensure durability over its lifespan.

   Hint

   Think about ways to reduce moisture retention in concrete.

6. 6.

   Discuss how you would assess a building for potential durability failures due to corrosion.

   Hint

   Evaluate not just the visible aspects but also underlying conditions.
