1. LECTURE 25 - Compressibility Properties

Try these first

1. 1.

   What does the term compressibility refer to?

   Hint

   Think about how a sponge behaves when you press it.

2. 2.

   What does the Swelling Index (C) measure?

   Hint

   Relate it to soil behavior.

3. 3.

   What does compressibility measure?

   • Volume change under pressure
   • Weight change under pressure
   • Temperature change under pressure

   Hint

   Think about materials that squash easily.

4. 4.

   The Swelling Index is related to which property?

   • True
   • False

   Hint

   Consider the behavior of soils.

5. 5.

   You have two soil samples: Sample A has a higher swelling index than Sample B. Predict how they would behave under an increase in moisture content and explain the implications for construction.

   Hint

   Consider the consequences of swelling on a building's foundation.

6. 6.

   Given an e-log σ' plot with points showing a steep slope, what conclusions can be drawn about the compressibility of the represented material?

   Hint

   Think about how compressible materials can affect structural integrity.
