Soil Phase Diagram for Dry Density An exclusive construction video for Civil Engineering Students



Civil Engineering Academy presents an informative video that is very useful for Civil engineering students who appear in PE exam. This construction video explains geotech issue concerning Soil Phase Diagram for Dry Density. Soil Phase Diagram is utilized to indicate the relationships that prevail amid the volumes and masses of each element concerning the soil sample.


To evaluate the degree of compaction, it is suggested to apply the dry unit weight, which defines the compactness of solid soil particles in a volume already assigned. The laboratory testing is undertaken to determine the utmost obtainable dry density for a soil already set with a standard amount of compactive effort.


While initiating the test, the dry density is not measured directly, and for example the bulk density and the moisture content are initially taken to estimate the dry density as , where = bulk density, and w = water content.

A sequence of samples of the soil are compacted at various water contents, and a curve is sketched involving axes of dry density and water content.
