In geotechnical engineering, soils are considered a three-phased material composed of which of the following?
Rock or mineral particles, water and air
Sand, clay, and silt
Water, sand, and gravel
Air, water, and organic matter
The water content of soil can be greater than 100%
True
False
Fill in the blank: The major soil solids are primary rock minerals, ranging in size from _______ to clays.
boulders
sand
silt
pebbles
The void ratio of the soil can be greater than 1
True
False
Which phase in soil may contain dissolved salts and other chemicals?
Solid particles
Liquid
Gas
Organic matter
Fill in the blank: The Saturated Condition has a saturation of (a) %.
Given the relationship between void ratio and porosity: e = Vv/Vs = Vv/(V - Vv), what is the void ratio (e) in terms of porosity (n)?
n/(1 - n)
n/(1 + n)
(1 - n)/n
n * (1 - n)
What is the ratio between the mass of water (Ww) in soils to the mass of solid particles (Ws) present called?
Water Content
Porosity
Bulk Density
Specific Gravity
Can the void ratio of the soil be less than zero?
Yes
No
What is the Bulk Unit Weight?
mass of all constituents per unit volume of soil
mass of water per unit volume of soil
mass of solids per unit volume of soil
mass of air per unit volume of soil
What is the Dry Unit Weight?
mass of soil particles (Ws) present per unit volume of soil
mass of water present per unit volume of soil
total mass of soil and water per unit volume of soil
volume of soil particles per unit mass of soil
Always (the saturated unit weight > Bulk unit weight > Dry unit weight)
Correct
Incorrect
