2.9. Swelling & Shrinkage

Try these first

1. 1.

   What is compaction?

   Hint

   Think about how we can pack more things into a limited space.

2. 2.

   Define swelling in the context of soil.

   Hint

   What happens to a sponge when it soaks up water?

3. 3.

   What happens to soil density during compaction?

   • Increases
   • Decreases
   • Remains the same

   Hint

   Think about how closely packed particles can fit.

4. 4.

   True or False: Dry soils exhibit less swelling than wet soils.

   • True
   • False

   Hint

   What happens when water is added to a dry sponge?

5. 5.

   Evaluate the potential consequences of not considering swelling and shrinkage in a planned construction project on clayey soil.

   Hint

   Consider the long-term effects of soil behavior on building integrity.

6. 6.

   Design a mitigation plan for a foundation built on expansive soils, including materials, construction techniques, and moisture management practices.

   Hint

   Focus on ways to control water influence effectively.
