The representation of different phases of soil with diagrams is called as phase diagram. For a soil, Gs = 2.7, the water content w =15% and the soil is 80% saturated. Water phase diagram. It is referred to as a Soil Phase Diagram. It is a very complex structure which can be simplified by taking a three phased diagram which have three different phased separated. It will not waste your time. The makeup of this soil sample can be illustrated visually as shown in Fig-1, where V represents volume, W represents weight, and the subscripts a, w, and s represent air, water, and solids. Find the void ratio, the porosity, the dry unit weight, and the degree of saturation for this soil. Ncei geomagnetic calculators.

Soil is compacted into a mould in 3-5 equal layers, each layer receiving 25 blows of a hammer of standard weight. A saturated sample of soil in a water content container weighed 60g. So if you separated the soil into its components it would look like this. Choosing appropriate calculation parameters. A schematic diagram of the three-phase system is shown in terms of weight and volume symbols respectively for soil solids, water, and air. On the sides of the diagram are variable names; numerical values are entered here during calculations. The apparatus is shown in Figure 1 below. The diagram which shows only two components of soil i.e., solids and air or solids and water is called two phase diagram, (figure 2.2 and 2.3) Soil mass is generally a three phase system as it contains soils solids along with water and air.
