Properties of Soil

The degree of saturation for a moist sample is 100 %.

The void ratio of a single sample will always be the same, whether it is in a dry, moist or saturated state.

The specific gravity of soil solids varies depending on its moisture content.

The unit weight of water is equal to 32.2 pound per cubic foot.

The degree of saturation for a dry sample is equal to zero.

Void ratio is the ratio between the volume of voids to the volume of soil mass.

The degree of saturation is the ratio of the weight of the water to the weight of the soil particles.

For saturated soils, the volume of voids is equal to the volume of water.

For a dry soil sample, the weight of the soil mass is equal to the weight of the soil solids.

For a dry soil sample, the unit weight of the soil mass is also equal to the unit weight of the soil solids.
