Atterberg Limits The Atterberg Limits (ASTM Test D-4318) define the ranges in moisture content that a soil will behave as a solid, plastic and liquid. The Liquid Limit (LL) of a soil is defined as the moisture content above which the soil behaves as a liquid, and the Plastic Limit (PL) is the moisture content above which the soil behaves

EXPERIMENT 7 ATTERBERG LIMITS

Sep 20, 2002  The Swedish soil scientist Albert Atterberg originally defined seven “limits of consistency” to classify fine-grained soils, but in current engineering practice only 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

Feb 06, 2015  Introduction (Description of soil samples) Soil is the first layer of the surface of the Earth. When a soil is mixed with an excessive amount of water, it will be in a somewhat liquid state and flow like a viscous liquid. As the moisture content increases the soil changes from solid to semisolid to plastic and then gradually changes to liquid. When this viscous liquid is dried, with the loss ...

Jul 30, 2021  The shrinkage limit is the point at which the soil changes from a rubber like material to a viscous liquid. • The swelling of clay is defined as the amount of water it takes to make the soil’s volume swell. The Atterberg limits can be used to differentiate between silt and clay, as well as distinct types of

Atterberg Limits and Indices. Atterberg defined the boundaries of four states of soil in the terms of “limits”. A fine-grained soil exists in different states depending on the amount of water in the soil system. The water content at which the soils change from one state to the other is known as consistency limits or Atterberg limit.

The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, plastic limit, and liquid limit.. Depending on its water content, a soil may appear in one of four states: solid, semi-solid, plastic and liquid.In each state, the consistency and behavior of a soil is different and consequently so are its engineering properties.
