Differentiate between compaction and consolidation with four points.

1 Answer

Answer :

Difference between compaction and consolidation: 

Compaction
Consolidation
Instant compression of soil under dynamic load is called compaction.
Gradual compression of soil under steady load is called consolidation
It is fast process.
It is very slow process.
It is artificial process.
It is natural process.
It is done to improve soil properties like bearing capacity, shear strength, impermeability etc.
It takes place due to structural load which does not improve soil properties.
Settlement is prevented due to compaction.
Settlement takes place due to consolidation. 
Compaction is done before construction of structure.
Consolidation takes place after construction of structure. 
Pore water pressure is not important in compaction.
Pore water pressure is very important in compaction.
Compaction does not go indefinitely.
Consolidation goes indefinitely.
