Q1. What is the difference between compaction and consolidation?
Ans. 
Compaction is a mechanical process to increase soil density, while consolidation is a gradual process of soil settlement under load.
• Compaction involves applying mechanical force to reduce air voids in soil, e.g., using rollers or vibratory plates.

• Consolidation occurs over time as water is expelled from soil pores under sustained load, e.g., clay soils settling after construction.

• Compaction is immediate and affects the ...read more
