Atterberg Limit
ATTERBERG LIMIT AND MOISTURE CONTENT
Introduction:
This report is to establish the Atterberg limit of s oil sample after performing and analyzing the tests performed in laboratory. Atterberg limit is used to differentiate between silt & clay , in various categories, and also to establish boundaries between each state of soil, i.e soild, semi-solid, plastic & liquid, and the change in soil behavior.
The method of Cone Penetrometer was used to determine the Liquid and Plastic limits of given soil sample. The objective of this test is to derive Plastic and Liquid limits from the results and classify the composition of the soil. The variation in composition of various soils can determine the effect on Atterberg Limit and understanding the plasticity of the soil is of vital importance as it has significance in any project.
Background Information:
The Atterberg Limits determines the plastic limits , the water content where soil starts to exhibit plastic behavior, and the liquid limits, where the water content of soil changes from plastic to liquid behavior. These limits are used to determine the consistency of a soil composition at various water content values.
The method used to determine the Liquid limit is verified to derive accurate measurement. The Cone Penetrometer test is performed for Liquid Limit in laboratory, Casagrande device method is not described in this report. Generally, in falling cone penetrometer test, the depth of penetration of the cone is measured and a curve of cone penetration against moisture content is produced. Liquid Limit is the moisture content at which the cone penetrates the soil by 20 mm and The Plastic Limit of the samples is found by rolling smaller specimens repeatedly
