What is Compaction?
Compaction is said to be compression of soil by expulsion of air from voids. It is a quick process, requires short term loading. Dynamic loading is applied during compaction, both cohesion and cohesionless soil can be compacted. Compaction is always done to get maximum dry density, which helps in improving bearing capacity. Compaction is done before start of construction. Mostly done in Construction of roads, Embankment, dam etc.,
What is Consolidation?
Consolidation is said to be compression of soil by expulsion of water from voids. It is a slow process, requires long term loading. Static or constant loading is applied (some times happen naturally), only cohesive soil can be consolidated. Consolidation is done naturally by structural loads from foundation. Consolidation is done naturally during the process of Construction. (Some times happen with natural settlement)
