Question

The liquid limit (LL), plastic limit (PL) and shrinkage limit (SL) of a cohesive soil satisfy the relation:

• A. LL $>$ PL $<$ SL
• B. LL $>$ PL $>$ SL
• C. LL $<$ PL $<$ SL
• D. LL $<$ PL $>$ SL

Hint:

Always remember the order: LL (highest), PL (middle), SL (lowest) for cohesive soils.

Answer 1

The Correct Option is B

Step 1: Define the limits.
- Liquid Limit (LL): Water content at which soil transitions from a plastic to a liquid state.
- Plastic Limit (PL): Water content at which soil transitions from a semi-solid to a plastic state.
- Shrinkage Limit (SL): Water content at which further moisture loss does not reduce soil volume.

Step 2: Relationship among the limits.
Based on definitions: \[\text{LL} > \text{PL} > \text{SL}.\]

Step 3: Conclusion.
Consequently, the established relationship is LL $>$ PL $>$ SL.
