   What is soil compaction?

   Hint

   Think about how you can compress air in a balloon.

2. 2.

   Define elastic settlement.

   Hint

   • Increases it
   • Decreases it
   • No effect

   Hint

   Recall what happens to a sponge when compressed.

4. 4.

   True or False: Both elastic and consolidation settlements are reduced by effective soil compaction.

   • True
   • False

   Hint

   Think of how packing something tighter changes its space.

5. 5.

   Consider how water content in clay influences density.

6. 6.

   Analyze the impact of using an admixture on soil performance in a residential project.

   Hint
