Show hintHide hint
Think about the numerical value compared to 35%.
Question 2.
What does the A line on the plasticity chart represent?
Show hintHide hint
It's linked with the plasticity index.
3Question 3.
What classification corresponds to a liquid limit greater than 50%?
- CL
- CH
- ML
Show hintHide hint
Think about the group symbols for different plasticity levels.
4Question 4.
True or False: The plasticity index is calculated as the difference of the liquid limit and plastic limit.
- True
- False
Show hintHide hint
Recall the definition of the plasticity index.
Question 5.
Given a soil sample with a plasticity index of 30%, liquid limit of 60%, and clay content of 70%, classify the soil and determine its liquidity index.
Show hintHide hint
Remember to calculate the plasticity index and use it to understand the liquidity.
Question 6.
A soil with well-defined low plasticity shows an activity of 0.5. What can we infer about its clay content?
Show hintHide hint
Reference the definition of activity and consider how it compares to the percentages discussed.
