LL is the abbreviation for which soil property?

• A. Laminar Load
• B. Lateral Load
• C. Liquid Limit
• D. Lactic Limit

Answer: (C)

In soil mechanics, LL denotes the Liquid Limit, one of the Atterberg limits that describe clayey soils’ consistency. The liquid limit is the water content at which soil changes from plastic to liquid behavior under standard conditions. It’s expressed as a percentage of water content by weight and is determined using a Casagrande-type test where the soil paste is placed in a groove; the water content at which the soil flows together across the groove after a specific number of blows is the LL. This property helps distinguish soils that flow readily when wet from those that remain more cohesive. The other terms listed aren’t standard soil properties: laminar load and lateral load describe forces, and lactic limit isn’t a recognized geotechnical term.
