1. Factors affecting Compaction

Try these first

1. 1.

   What is MDD?

   Hint

   Think about density in relation to water content.

2. 2.

   What happens to density beyond OMC?

   Hint

   Consider what happens when more water is added.

3. 3.

   What does MDD stand for?

   • Maximum Density Drought
   • Maximum Dry Density
   • Moisture Density Disc

   Hint

   Focus on the terms used in soil compaction.

4. 4.

   True or False: Fine-grained soils achieve higher density at lower water content than coarse-grained soils.

   • True
   • False

   Hint

   Revisit the differences in soil types.

5. 5.

   A construction site has three soil types: clay, sandy, and gravel. Create a compaction approach for an optimal foundation considering the unique properties.

   Hint

   Look into how each soil responds to moisture and compactive efforts.

6. 6.

   Explain the consequences of improper compaction leading to structural failure, citing real-world examples.

   Hint

   Think about famous constructions that have collapsed due to compaction issues.
