2.1. Density

Try these first

1. 1.

   What is the purpose of adding admixtures to soil?

   Hint

   Think about how we change materials for better performance.

2. 2.

   Define density in the context of soil.

   Hint

   Relate it to the concept of compaction.

3. 3.

   What does adding admixtures to soil do?

   • Increases permeability
   • Improves soil stability
   • Lowers density

   Hint

   Think of their purpose in construction.

4. 4.

   True or False: Increased compaction always results in lower shear strength.

   • True
   • False

   Hint

   Review how particle interactions change.

5. 5.

   Evaluate the impact of adding 10% lime to a clay soil's properties after compaction.

   Hint

   Consider how lime might change the particle size distributions and cohesion.

6. 6.

   Compare the performance of a dry compacted soil versus a wet compacted soil in a foundational application.

   Hint

   Focus on how moisture content alters soil behavior under stress.
