Question

In a soil sample, specific Gravity of soil particles is 2.5 and the void ratio is 0.5. The density of the soil sample when it is fully saturated with water is ______kg/m^3 ( assuming density of water 1000kg/m^3 and no volume change of the soil sample with saturation

Answer 1

Explanation:

A soil sample has a porosity of 41%, a moisture content of 15.2% and a specific gravity of 2.65. Determine the degree of saturation and the air void ratio.

We can't directly calculate the degree of saturation or the air void ratio. First we need to find the void ratio because e is needed to find the answers.

The porosity is given, therefore we can find the void ratio.

(or 58%)

Air void ratio, Av = n (1-Sr) = 0.41 (1-0.58) = 0.1722 (or 17.2%)

(or 17.2%)
