The liquid limit is one of the atterberg limits and this test determines the water content at which the behavior of clayey soil changes from plastic to liquid OR It is the minimum moisture content at which a soil flows upon application of very small shear force and this limit is also known as an upper plastic limit. c. The prepared paste is then transferred to the cylindrical cup of the cone penetrometer apparatus. And if slippage occurs then we should discard that soil pat and re-do the whole procedure. Procedure of The Liquid Limit Test of Soil by Casagrande Method:-. Repeat the above same procedures to 5 or 6 times by adding water to the same sample. The precise definition of the liquid limit is based on standard test procedures. Thoroughly mix the soil with a small amount of distilled water until it appears as a smooth uniform paste. [1] The liquid limit of a soil is the water content at which the soil behaves practically like a liquid, but has small shear strength. Procedure: Liquid Limit: 1-Determine the weight of the three moisture cans (W1). The liquid limit of fine-grained soil is the water content at which soil behaves practically just like a liquid, but have small shear strength. Remove from the container the soil to be used for the liquid limit test. Procedure of Liquid Limit Test : Take about 30 to 40 gm of given soil passing through 425 microns IS sieve in evaporating disc. These test methods cover the determination of the liquid limit, plastic limit, and the plasticity index of soils as defined in Section 3 on Terminology. Flow Index = 9.

The standard liquid limit test device was designed by Arthur Casagrande in the 1930s based on the procedure developed by Albert Atterberg; therefore, the liquid limit test is sometimes called the Casagrande test. How To Make Concrete Test Cylinders ASTM C31 Procedure pdf. Atterberg limits are defined as the water corresponding to different behaviour conditions of fine-grained soil (silts and clays). 1. Test Procedure Title Archive Form; . 3. Atterberg Limits Tests establish the moisture contents at which fine-grained clay and silt soils transition between various states (soil, semi-solid, plastic, and liquid), which is an important step in determining the soil's strength, consistency and behavior. SCOPE. Hence plastic limit by the cone penetration test obtained by redefining plastic limit in terms of strength as that water content that gives a 100-fold increase in shear strength over that at the liquid limit will henceforth in this study be called PL 100. Atterberg Limits Test Procedure: Liquid Limit is measured by spreading a portion of the soil sample in the brass cup of a liquid limit machine and dividing it using a grooving tool. The value of liquid limit helps in classification of fine grain soil. Put 250 gm of air-dried soil, passed thorough 425 m m sieve, into an evaporating dish.
