What does LL stand for in soil mechanics?

• A. Linear Limit
• B. Load Level
• C. Layer Length
• D. Liquid Limit

Answer: (D)

Liquid Limit is the water content at which soil transitions from a plastic to a liquid state, one of the Atterberg limits used to describe soil consistency. It’s found with a standard test (Casagrande method) where a soil paste in a cup is worked with a groove and a series of blows are delivered; the water content at which the groove closes after a defined number of blows (typically 25) defines the liquid limit. Soils with higher liquid limits are more plastic and clay-rich, meaning they flow more readily with moisture, while lower values indicate stiffer, less plastic soils. The other terms listed aren’t standard descriptors in soil mechanics.
