welcome back you are watching youtube channel civil engineering easy in this short video i will discuss the basic and important topic in soil mechanics that is what is the main difference between compaction and consolidation of soil following out the difference between compaction and consolidation .
First main difference is that the compaction is the compression of soil by the expulsions of air from the wires of the soil while the consolidation is the compression of soil by the expulsions of water from the wires of the soil the compaction is a quick process while the consolidation is a slow process .
Short-term loading is required for the compaction process while for the consolidation long-term loading is required loading is applied in a dynamic way there is compaction with the help of different types of rollers while in the case of consolidation loading is static and constant any type of soil either it is cohesion or cohesion list can be .
Compacted while consolidation applies to cohesive soils only especially for the low permeable clay degree of saturation of soil to be compacted should be less than 100 percent while in the case of consolidation degree of saturation of the soil to be consolidated should be 100 percent with the help of compaction the shear strength of soil increases .
Similarly the shear strength of the soil increases in consolidation wide ratio compressibility and permeability decreases in both compaction and consolidation bearing capacity and settlement characteristic improve in compaction and consolidation compaction is done properly in order to .
Get maximum dry density of soil compaction is done purposely in order to get the maximum dry density of soil consolidation of soil occurs naturally due to the structure loads from the foundations compaction is done before the construction of a structure while consolidation begins naturally along with the construction work to construct .
Road earthen dams embankments etc compaction is useful while the foundation soil properties will improve over long period due to consolidation that's what we discussed the major difference between compaction and consolidation see you in the next video .
