According to IS 2720 (Part 8) - 1983, which deals with the determination of the optimum moisture content (OMC) and maximum dry density of soils for compaction, the optimum moisture content (OMC) for cohesive soils (like clay) generally falls within the range of 12–16%.
Additional InformationOptimum Moisture Content
-
OMC is the moisture content at which the soil can be compacted to its maximum dry density.
-
At this moisture level, cohesive soils exhibit their best compaction characteristics, leading to the highest strength and stability.
-
Cohesive soils have a higher OMC compared to non-cohesive soils (like sand), as they require more water to achieve maximum compaction due to their finer particles and adhesive properties.
