The soil will behave as a two-phase system when its void space is filled by either water or air alone.Such condition is possible when the soil is either fully saturated or fully dry.. Three-Phase Diagram of Soil. Let us consider the 3 phase diagram of a partially saturated soil. CE 210 SOIL MECHANICS AND FOUNDATION ENGINEERING I SaMeH Page 15 Three Phase Diagram. Subscripts v and t stand for voids and total respectively. Liquids and gases are mostly water and air, respectively. These two (water and air) are called voids which occupy between soil particles. But, when the soil mass is partially saturated, its void space will be filled up by water as well as air.

It is referred to as a Soil Phase Diagram. Moisture Content: Mass of … V is for volume, M is for mass. For many civil engineering purposes, the liquid may be considered to be water and the gas as air (Figure 1 and 2) with the exception geoenvironmental, and oil and gas applications. PHASE DIAGRAM 7. Draw a phase diagram. Soil deposits consist of the soil particles and the void space between the particles. The weight of total voids is equal to the weight of Water. Generally soil contains solid particles, water and air (three phase are present). The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas. The above values have been provided with both imperial and metric units. Degree of saturation for this soil sample is defined as volume of water to the volume of voids this soil sample contains. There are a variety of parameters used to describe the relative proportions of air, water and solid in a soil.
