Thoroughly mix the soil with a small amount of distilled water until it appears as a smooth uniform paste. When determining the plastic limit, two procedures for rolling portions of the test specimen are provided as follows: Plastic Limit Rolling Procedure 1 (Hand Rolling), and Plastic Limit Rolling Procedure 2 (Using the Rolling Device). 1.4 The plastic limit test, Method for Plastic Limit, is performed on material prepared for the liquid limit test. THEORY: The liquid limit is the moisture content at which the groove, formed by a standard tool into the sample of soil taken in the standard cup, closes for 10 mm on being given 25 blows in a standard manner. IS - 2720 (Part 5) - 1985 recommends the following procedure for determination of liquid limit with a single trial: 1. Table 2. i) Place a portion of the paste into the cup of the liquid limit device. Liquid limit of a particular soil is defined as the water content at which cone penetrates the soil up to 20 mm in 5 seconds But, since it is difficult to have such a water content of soil which gets us the exact 20 mm of penetration in 5 seconds, we repeat the whole procedure at least three more times with different water contents. Also, clean the grooving tools. The Liquid Limit (WL) of the soil sample is the moisture content correspond ing to a cone penetration of 20 mm and shall be expressed to the nearest whole number. 150gm of prepared sample is taken. Liquid limit is obtained by plotting graph to number blows (log scale) against . About 120 g of oven dry soil sample passing 425 micron IS sieve shall be mixed thoroughly with distilled water in the evaporating dish or on the fiat glass plate to form a uniform paste.

Besides the consistency limits, the plasticity index, liquidity index, and consistency index have been used to correlate with engineering properties. Add distilled water and mix it thoroughly and is left for a suitable maturing time, generally 15 to 30 mins for an average soil. The plastic limit, liquid limit, and shrinkage limit of soils are all test results obtained by direct measurements of the water content following the standard test methods. Determine the water content of the soil contained in the containers in accordance with Test Method D 2216. 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. Plastic Limit 21 20. Procedure. 1.1 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. Select another 1.5 to 2.0-g portion of soil from the plastic limit specimen and repeat step 1 and 2 until the container has at least 6 g of soil. ST - 18OC Electric Liquid Limit Device. The values of liquid limit are required to calculate flow index, toughness index etc. If a valid penetration still cannot be obtained the test portion shall be returned to the humidifier or air tight container for further curing and Procedures 6(f) to 6(r) repeated. The soil passing 425 micron sieve is used in this test. Plastic limit Plastic limit is a test that involves rolling out a thread of the fine portion of . For each laboratory test procedure described, sample calculation(s) and graph(s) are inCluded. From liquid limit test, the compression index may be estimated, which is used in settlement analysis. In coarse textured soils it is usually difficult to control water content for the liquid limit test and those soils may not even have a plastic limit. Can Number 5 207; Mass of Can, M1 (g) 29 21. Also, blank tables for each test are provided at the end of the manual for student The liquid limit (LL) is an important parameter for soil classification systems. Plastic Limit Data Table. Liquid Limit (LL) is the water content at which soil changes from a plastic to a liquid state when the soil specimen is just fluid enough for a groove to close when jarred . Test Procedure a) Mix about 300 g of the prepared soil (after 24 hours maturing) with a little distilled water if necessary, using two spatulas, for at least 10 minutes. The plastic state, 3.

LIQUID LIMIT TEST . Continue Reading How To Find Liquid Limit and Plastic Limit Test of Soil. . c. The prepared paste is then transferred to the cylindrical cup of the cone penetrometer apparatus. 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. 3. The Atterberg limits or consistency limits The "liquid limit" (LL) is the minimum moisture content at which a soil is assumed to flow under its own weight, which corresponds to 25 blows in the Casagrande test or 20 mm penetration in the Penetrometer test The "shrinkage limit" (SL) is the water content 6- Liquid Limit Test Procedure.

Liquid Limit Test used to evaluate the relationship between the moisture percentage of a soil sample and the number of blows required to close a groove made into the soil, and therefore to determine when a clay soil changes from a plastic to a liquid state. The liquid limit of a soil is the water content at which the soil behaves practically like a liquid, but has small shear strength. Atterberg limits are defined as the water corresponding to different behaviour conditions of fine-grained soil (silts and clays). The moisture content when the groove closes for 1/2in after 25 drops of the cup is defined as the Liquid Limit. The liquid state, 2.
