What is plasticity in soil?
Think about how clay behaves when wet.
Define the plasticity index.
Consider it as the difference between liquid and plastic limits.
What is the formula for the 'A' line on the plasticity chart?
Think about how we derived it during class.
True or False: A higher plasticity index indicates a more plastic soil.
What does plasticity index measure in terms of soil behavior?
Given a soil sample measured: Liquid Limit = 62%, Plastic Limit = 32%, and moisture content = 48%. Determine its classification and liquidity index.
Don’t forget to apply the index formulas correctly to classify the soil.
A researcher finds a soil with 45% liquid limit, 25% plastic limit, and 80% clay content. Calculate its activity and suggest possible implications if used for construction.
Use the ratios properly to assess the suitability of the soil.
