It does not store any personal data.The consistency limits (liquid limit LL and plastic limit PL) are among the most commonly performed tests in geotechnical engineering practice, being used for classification of fine-grained soils and in deducing other parameters (e.g., shear strength, permeability, compressibility), necessary for preliminary design/assessments, via numerous correlations built up over the decades.

Liquid limit of soil can be used to predict the consolidation properties of soil while calculating allowable bearing capacity & settlement of foundation. It gives us information regarding the state of consistency of soil on site. Value of liquid limit is used to classify fine grained soil. What is the liquid limit of sand?Īn Atterberg Limit corresponds to the moisture content at which a soil sample changes from one consistency to another….The plastic limit (PL) Soil type The water content at which the soils change from one state to the other are known as consistency limits or Atterberg’s limit. The Atterberg limits can be used to distinguish between silt and clay, and to distinguish between different types of silts and clays. What is the importance of Atterbergs limit in geotechnical engineering?

The test is based on the relationship between moisture content and the penetration of a cone into the soil sample under pre-set For determining the liquid limit of soils. It is a static test depending on the soil shear strength. The Cone Penetrometer is used to carry on liquid limit tests onsoil samples. Which apparatus uses the liquid limit test? The undrained shear strength-water content relationship has been found to be log-linear for a wide range of water contents beginning from lower than the plastic limit to higher than the liquid limit. Undrained shear strength of a soil at the liquid limit can be considered to be around 1.7 kN/m2. How does liquid limit affect the shear strength of soil? The plastic limit is the lower limit of the plastic state. The plastic limit (PL) The percentage moisture content at which a soil changes with decreasing wetness from the plastic to the semi- solid consistency or with increasing wetness from the semi-solid to the plastic consistency. What is the diameter of the sieve that is used for finding the liquid limit? Explanation: 425 micron sieve is used as a standard, for filtering the given specimen. Which is used for finding liquid limit is?Ĥ. As the starting procedures of liquid limit test and plastic limit test are common, the both tests are executed at the same time in most of the purposes. Plastic limit test is one of the laboratory tests used internationally to differentiate or classify soils into groups. What is the purpose of plastic limit test? These are used to calculate the plasticity index (PI = LL − PL), which is the measure of sensitivity of the soil to changes in its moisture content. The two limits associated with plasticity of soil are liquid limit (LL) and plastic limit (PL). What is the purpose of liquid limit and plastic limit? 7 What is the importance of Atterbergs limit in geotechnical engineering?.6 How does liquid limit affect the shear strength of soil?.3 What is the importance of determining the Atterberg limits?.2 What is the purpose of plastic limit test?.1 What is the purpose of liquid limit and plastic limit?.
