1.2. Mechanism of Creep

Try these first

1. 1.

   What is creep in concrete?

   Hint

   Think about how materials react over time under pressure.

2. 2.

   Which component of concrete primarily contributes to creep?

   Hint

   Consider the material that holds the concrete together.

3. 3.

   What is the primary cause of creep in concrete?

   • Thermal expansion
   • Moisture movement
   • Chemical reaction

   Hint

   Think about water's role in how concrete behaves over time.

4. 4.

   True or False: Higher water-cement ratios contribute to less creep.

   • True
   • False

   Hint

   Consider how moisture changes material properties.

5. 5.

   A new concrete mix has a water-cement ratio of 0.6. Predict how this might affect the creep behavior compared to a mix with a 0.4 ratio.

   Hint

   Think about the relationship between moisture and deformation.

6. 6.

   Analyze the impact of factors like age at loading and temperature on the creep coefficient of concrete used in a high-rise building construction.

   Hint

   Consider how age and environment interplay with strength development in concrete.
