Define void ratio.
Think about how voids are measured in relation to solids.
What is porosity?
It's a percentage measurement of void space.
What does the void ratio (e) represent?
Think about how voids relate to solids.
True or False: The degree of saturation (S) can exceed 100%.
Consider what saturation means.
A soil sample has a dry unit weight of 18 kN/m³ and a specific gravity of 2.65. Calculate the void ratio and porosity of the soil.
Remember the formulas relating these parameters.
If the bulk unit weight of a saturated soil is 22 kN/m³ and the dry unit weight is 20 kN/m³, what is the water content?
Think about the relationship between bulk and dry unit weights.
