The Atterberg limits (Liquid Limit, Plastic Limit, and Shrinkage Limit) describe the boundaries of consistency for fine-grained soils. The Liquid Limit (LL) is particularly significant as it defines the moisture content at which the soil transitions from a plastic state to a liquid state. This is a critical property fo...
