Jul 10 2005 0183 32 The bulk density of soil depends greatly on the mineral make up of soil and the degree of compactionThe density of quartz is around 265 g/cm³ but the dry bulk density of a mineral soil is normally about half that density between 10 and 16 g/cm³ In contrast soils rich in soil organic carbon and some friable clays tend to have lower bulk densities...

Proctor compaction test

The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry densityThe test is named in honor of Ralph Roscoe Proctor who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil...

The determination of maximum dry density and optimum moisture content of the soil is a measure of compaction level of soils This can be measured by mainly two methods Standard Proctor Compaction Test and Modified Proctor Compaction TestBoth the tests help to determine the optimum moisture content that is required for soil to attain maximum compaction ie maximum dry density for...

Water content

Water content or moisture content is the quantity of water contained in a material such as soil called soil moisture rock ceramics crops or woodWater content is used in a wide range of scientific and technical areas and is expressed as a ratio which can range from 0 completely dry to the value of the materials porosity at saturation It can be given on a volumetric or mass...
