2- The 3 main physical states of clay (in a volume-moisture relationship) are _____________, _________, and ______________.

3- How many blows per second is the liquid limit device cranked?

4- Liquid Limit is the lower moisture limit of what state of clay? Draw the diagram showing the moisture contents vs. states of clay.

5- In the PL test, what is the diameter of the thread that we must roll that determines the PL moisture? What is the ASTM standard that tells you that?

Solution

1. The two kinds of rock sedimentation are physical and chemical sedimentation

2. The 3 main physical states of clay are : Slip--watered down clay, Plastic--workable stage, Leather-hard--stiff

3. 25  blows per second is the liquid limit device cranked
