Solved.
The two main definitions of rock are as follows: - Answer Sowers and ASTM
The two main definitions of soil are as follows: - Answer Das and ASTM
Das - Answer An uncemented aggregate of mineral grains and decayed organic matter (solid
particles) with liquid and gas in the empty spaces between the solid particles
ASTM (formerly American Society for Testing and Materials): - Answer Sediments or other
unconsolidated accumulation of solid particles produced by the physical and chemical
disintegration of rocks, and which may or may not contain organic matter.
Compaction - Answer the densification of soil by removal of air and water by means of
mechanical energy.
the zero air void line (Z.A.V.) is the maximum theoretical density a soil can be compacted to. -
Answer true
Modified proctor energy is less than standard Procter energy. - Answer false
Given the wet unit weight equal to 118 pff and a moisture content of 10% calculate the dryer
unit way it to one place after the decimal point. - Answer 107.3
The following are types of ground water - Answer All: confined aquifer, unconfined aquifer,
perched ground water
Hydraulic conductivity (k) depends upon which of the following soil parameters - Answer
Grain size distribution, void ratio, fluid viscosity (temperature), and degree of saturation
As the compact of effort increases the optimal moisture constant while increasing the maximum
density will increase. - Answer false
Soil compaction is accomplished by which of the following mechanisms - Answer Vibration,
manipulation, pressure, and impact
Water moves naturally from points of low energy to points of high-energy - Answer false
