XIII. Soil Density
Soil Density Test is one of the three physical test indices, gravity, density and percent moisture.
Combined with Percent Moisture and Soil Gravity, Soil Density can be used to calculate out six
physical indices, Dry Density, Saturation Density, Buoyant Density, Pore Space Ratio, Porosity and
Saturation. Soil Density measurement is required no matter in lab test ， field investigation or
construction quality control.
1. Soil Wet Density
𝜌𝜌
𝜌𝜌 =
𝑚𝑚
𝑉𝑉
In the formula:
𝜌𝜌
——Soil Wet Density (
𝑔𝑔 / 𝑐𝑐𝑚𝑚
3
)
𝑚𝑚
——Total Mass of Wet Soil (
𝑔𝑔
)
𝑉𝑉
——Volume of the Soil (
𝑐𝑐𝑚𝑚
3
)
Usually in the case of no special instructions, soil density refers to the Soil Wet Density. Therefore,
the soil density is not soil particle density, and the soil particle density does not refer to the gravity
of soil particle or soil. Although the density and gravity of the soil particle are the same on numerical
value, the two bear different physical meanings. Density is a dimensional quantity while gravity is a
non-dimensional quantity.
