The optimum moisture content of a clay soil is 24%, whom compaction test is conducted at 30% moisture content, its structure will be Correct Answer Dispersed

Concept-

Compaction of soil is the pressing of soil particles close to each other by mechanical methods. Air during compaction of soil is expelled from the void space in the soil mass and therefore the mass density is increased.

Compaction of soil is done to improve the engineering properties of the soil. Compaction of soil is required for the construction of earth dams, canal embankments, highways, runways and many other structures.

Effect of Compaction on Soil Structure-

Soils compacted at a water content less than the optimum generally have a flocculated structure. Soils compacted at water content more than the optimum usually have a dispersed structure.

Effect of Compaction of Soil on Permeability

The permeability of soil depends upon the size of voids. The permeability of soil decreases with an increase in water content on the dry side of optimum water content.

Given Data and Analysis-

The optimum moisture content of clay soil is 24%, whom compaction test is conducted at 30% moisture content.

The moisture content is more than the optimum moisture content, so the soil will have a dispersed structure of the soil.
