Yes! Atterberg limits are consistency limits of soil that define the water content at which the soil changes from one state to the other on addition or removal of water content. Fine-grained soil, especially clayey soils changes their attributes or characteristics upon addition or expulsion of water content.
Liquid Limit. In order to standardize the test procedure for Atterberg limits, Casagrande defined liquid limit as the water content at which a groove cut in a soil pat, by a standard grooving tool, will require 25 blows to close for 13 mm when the LL-apparatus cup drops 10 mm on a hard rubber base (Fig. 2).The standardized test requires testing five to …
The Atterberg Limits Test are a group of standardized tests that are performed on the fraction of fine-grained soils, such as silts and clays, that will pass through a No. 40 or 425µm standard sieve to determine their properties under different moisture contents. There are three Atterberg Limits Tests that are commonly performed: liquid limit test, plastic …
The limit is defined as the moisture content, in percent, required to close a distance of 0.5 inches along the bottom of a groove after 25 blows in a liquid limit device. It is difficult to adjust the moisture content in the soil to meet the required 12.5 mm (0.5 in.) closure of the groove in the soil pat at 25 blows.

3.2 Determination of Atterberg Limits 3.2.1 Scope. As the moisture content of a soil decreases the soil passes from the liquid state to the plastic state to the solid state. The range of moisture contents over which the soil is plastic is used as a measure of the plasticity index. The points at which a soil
ISO/TS 17892-12:2004 specifies methods of test for the determination of the Atterberg limits of a soil. The Atterberg limits comprise the liquid limit, plastic limit and shrinkage limit.

2.2.5 Plastic limit. Plastic Limit ( PL) is an Atterberg limit defined as the moisture content at the point of transition from semisolid to plastic state (Das and Sobhan, 2013 ). Plastic limit is related with the shear strength of soils as it increases the shear strength decreases ( Sharma and Bora, 2003 ).
consistency limits and the moisture content obtained at various pressure intensities. The results also strongly suggest that the moisture tension test can be used on a routine basis for determining the consistency limits of soils. •THE Atterberg limits have been extensively used for identifying engineering proper

The limit is defined as the moisture content, in percent, required to close a distance of 0.5 inches along the bottom of a groove after 25 blows in a liquid limit device. Liquid Limit (LL or wL) - the water content, in percent, of a soil at the arbitrarily defined boundary between the semi-liquid and plastic states. Atterberg Limits Chart.
1. There are variations in the Atterberg limit values. However, the magnitude of the variations are relatively small. The Atterberg limits can, therefore, be regarded as reproducible from the engineering standpoint. 2. The amount of experience an operator has does affect the variations of the Atterberg limit values. 3.
Atterberg Limits. In 1911, the Swedish agriculturist Atterberg divided the entire range of soil state (from liquid to solid state) into four stages, which is known as Atterberg Limits or Consistency Limits. 1. The liquid state, 2. …
1.4 The plastic limit test is performed on material prepared for the liquid limit test. 1.5 The liquid limit and plastic limit of soils (along with the shrinkage limit) are often collectively referred to as the Atterberg limits. These limits distinguished the boundaries of the several consistency states of plastic soils.
The Atterberg limits test is a classification test and is performed to aid in the classification of soil and its plasticity characteristics. It evaluates the shrink/swell potential of near-surface soil and can be used to distinguish between silt and clay and its different types. It gives the shrinkage limit, plastic limit, and liquid limit of ...

The Atterberg Limits, the Liquid Limit, Wl, and the Plastic Limit, W p, define the range of water content over which a clay soil is plastic. The Plasticity Index, I P, is the difference between the Liquid and Plastic Limits: [4] I P = W l − W p. For a natural clay soil, which may contain silt and sand sized grains, the Activity is.
The 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. The plastic state is the condition at which the soil can be remolded to any shape without any development or cracks.
40 5%, silt faction 17.6 - 60.7%, sand fraction 14.5 - 54.6% and gravel content from 0.0 – 24.8%. The result of Atterberg Limit test on the soil in the research area showed a liquid limit ranging from 29 – 73%, plastic limit ranging from 21 – 35% and plastic index from 13 – 34%. The specific sravity ranges from 2.40 to 2.70.
