Determination of Maximum Dry Density and Optimum Moisture Content …

The water content corresponds to this point is called the Optimum water content (O.W.C) or optimum moisture content (O.M.C). Fig.4. Compaction Curve of Soil. The graph shown in figure-3 is the compaction curve. Initially for a water content lesser than O.M.C the soil is rather stiffer in nature that will have lots of void spaces and porosity.

What is Free Moisture Content in Aggregates?

What is the ideal aggregate moisture state. The ideal aggregate moisture state is the balance between too wet and too dry. It refers to the moisture content at which the aggregates are neither in excess of free moisture nor excessively dry. Achieving this state is crucial in ensuring the proper workability and strength of the resulting mixture.
