The soil is particulate materials which can contain all three phases of matter (solid, liquid, and gas). The solid portion represents actual soil’s particles, while the liquid and gas portions represent voids existed between soil’s particles. The interaction between these three phases can be illustrated and described using a “Phase Diagram”, see Figure 1.

Common soil parameters used to define the relative portions in a soil mass are summarized in Table 1.
Table 1: Common Soil Weight-Volume Parameters and their Typical Values
Several formulas were developed to express the relationships between weight-volume parameters of the soil. The following table summarizes the most common relationships used in the foundation engineering:
