4.1. For Creep

Try these first

1. 1.

   What is creep in concrete?

   Hint

   Think about how deformation changes over time under pressure.

2. 2.

   Name one factor that affects creep.

   Hint

   Consider how the material composition influences properties.

3. 3.

   What is the definition of creep?

   • A sudden deformation
   • Gradual deformation over time
   • Instantaneous elastic deformation

   Hint

   Think about the difference between gradual changes and sudden changes.

4. 4.

   Is drying creep influenced by moisture levels?

   • True
   • False

   Hint

   Consider how moisture dynamics interact with the material properties.

5. 5.

   A concrete beam of high-strength mix (w/c ratio of 0.30) shows significant creep after 10 years. Discuss the potential impacts on structural integrity and preventative strategies.

   Hint

   Reflect on how preventing moisture loss can be key.

6. 6.

   Analyze how varying environmental conditions (temperature and humidity) could affect the creep of normal vs. high-strength concrete.

   Hint

   Consider the interplay between concrete characteristics and environmental effects.
