Soil Mechanics Lecture Notes: Plasticity and Structure of Soil - Prof. Mante, Slides of Soil Mechanics and Foundations

Colegio de San Juan de Letran Calamba (CSJLC)Soil Mechanics and Foundations

Prof. Jose Mante

These lecture notes delve into the plasticity and structure of soil, covering key concepts like liquid limit, plastic limit, shrinkage limit, and activity. They provide a comprehensive overview of atterberg limits, their determination, and their significance in soil mechanics. The notes also include practical examples and references to relevant standards and literature.

4.1: Introduction •^ A Swedish scientist named^ Atterberg

developed a method to describe the^ consistency of fine‐grained soils

with varying moisture contents.

-^ The behavior of soil can be divided into four basic states—

solid, semisolid, plastic, and liquid.^ jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.2: Liquid Limit (LL)^ jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.2: Liquid Limit (LL) •^ From the analysis of hundreds of liquid limit tests, the

U.S. Army Corps of Engineers (1949)^ proposed an

empirical equation^ of the form. • Equation (4.3) generally yields good results for the

number of blows between 20 and 30. jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.2: Liquid Limit (LL) •^ Another method of determining

liquid limit^ that is popular in Europeand Asia is the Fall Cone Method^ (British Standard—BS1377).

-^ In this test the liquid limit is defined as the moisture content at whicha standard cone of^ apex angle 30°

and^ weight of 0.78 N (80 gf)^ will penetrate a distance^ d = 20 mm^ in 5 seconds jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.2: Liquid Limit (LL) •^ Fall Cone Method. Flow index can be defined as jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.3: Plastic Limit (PL) •^ The^ Plastic Limit^ is defined as the moisture content in percent, atwhich the soil crumbles, when rolled into threads of

3.2 mm (1/8 in.) diameter. jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.3: Plastic Limit (PL)^ jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.3: Plastic Limit (PL) •^ The^ Plasticity Index (PI)^ is the difference between the liquid limit andthe plastic limit of a soil. jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.4: Shrinkage Limit (SL) •^ The moisture content, in percent, at which the volume of the soilmass ceases to change is defined as the

Shrinkage Limit.

-^ ASTM D427 – Test Method for Shrinkage Factors of Soils by theMercury Method (Withdrawn 2008). •^ ASTM^ D4943^ ‐^ Standard^ Test

Method^ for^ Shrinkage^ Factors

of Cohesive Soils by the Water Submersion Method.jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.4: Shrinkage Limit (SL)^ jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.4: Shrinkage Limit (SL) •^ Shrinkage ratio , which is the ratio of the volume change of soil as apercentage^ of^ the^ dry^ volume

to^ the^ corresponding^ change^

in moisture content. jbmamburam_CIEN 3113_2nd Sem AY 2024‐

4.4: Shrinkage Limit (SL) •^ The maximum expected^ volumetric shrinkage

and linear shrinkage at given^ moisture contents (w)^ can be calculated as: • Linear shrinkage • Typical values of shrinkage limit for some clay mineralsjbmamburam_CIEN 3113_2nd Sem AY 2024‐
