What is the use of optimum moisture content?

The Optimum moisture content (OMC) or Optimum Water Content (OWC) is the moisture content at which the soil attains maximum dry density. This OMC value is with respect to the specific amount of compaction energy applied to the soil.

What is the use of maximum dry density?

Maximum dry density (MDD) of stabilized soils is generally an important factor in determining the soil suitability or unsuit- ability for stabilization.

What is the purpose of a dry density test?

The purpose is to determine the number of passes to be made by the roller at various combinations of static or vibratory rolls to achieve maximum density for this depth of the material using this roller.

What is optimum density?

The concept of optimum density 7, i.e., the density which will give the maximum real income per head with given resources, is used in population theory.

What is dry density?

It refers to the density of the soil, when it is taken in the dry state. The soil mass is commonly a mixture of air, water and soil solids. The dry density refers to the soil solids. It is otherwise called as dry unit weight of soil.

What is dry of optimum?

It is known that the soil becomes dense when it undergoes compaction. So, if the amount of water added is less than the optimum moisture content then it is called as dry of optimum compaction. If the amount of water added is more than the optimum moisture content then it is called as wet of optimum compaction.

What is OMC and MDD?

MDD – Maximum Dry Density. MWD – Maximum Wet Density. OMC – Optimum moisture Content. Zero Air Voids – is the relationship between dry density and corresponding moisture contents, for a specific particle density, assuming that all of the voids are completely filled with water.

What is MDD in civil engineering?

it occupies the void spaces between solid grains and hence as the water content increases dry density of soil decreases. Maximum Dry Density (MDD) is the dry density of soil corresponding to Optimum Moisture Content.

What is moisture density?

Moisture content of soil is defined as the ratio of mass of water to the mass of solids present in the soil sample. It is represented by “w”. Dry density of soil is defined as the ratio of Mass of solids to the total volume of the soil.
