WebSep 20, 2002 · two of the limits, the liquid and plastic limits, are commonly used. (A third limit, called the shrinkage limit, is used occasionally.) The Atterberg limits are based on the moisture content of the soil. The plastic limit is the moisture content that defines where the soil changes from a semi-solid to a plastic (flexible) state. The WebWhat Does Shrinkage Limit (SL) Mean? Shrinkage limit (SL) is the moisture content at which a fine-grained soil does not change the volume on drying; the moisture loss is …

The shrinkage limit (SL) is defined as the water content at which the soil changes from a semi-solid to a solid state. At this moisture content the volume of the soil mass ceases to change with further drying of the material. The shrinkage limit is less frequently used than the liquid and plastic limits. The shrinkage … See more The Liquid Limit (LL or wLL), also known as the upper plastic limit, is the water content at which the soil changes from the liquid state to a plastic state. It is the minimum moisture … See more The Plastic Limit (PL or wPL), also known as the lower plastic limit, is the water content at which a soil changes from the plastic state to a … See more Plasticity Index (PI or IP) is calculated as the Plastic Limit subtracted from the Liquid Limit and is an important value when classifying soil types. PI = LL - PL See more
WebThe water content at which the soils change from one state to the other is known as consistency limits or Atterberg limit. The liquid state is the state of a fine-grained soil at which the soil will flow on its own weight.

Depending on its water content, soil may appear in one of four states: solid, semi-solid, plastic and liquid. In each state, the consistency and behavior of soil are different, and consequently so are its engineering properties. Thus, the boundary between each state can be defined based on a cha… french fries in olive oilWebGeneral description.
