1.1 Introduction
1.1.1 OBJECTIVE
To determine the natural moisture content of a soil sample.
1.1.2 Learning Outcome
Understand the concept of Phases of Soil and Block Diagram
Define Moisture Content and Explain its Uses
Describe Lab Method for Determining Moisture Content of Soils
Perform the Moisture Content Test
Determine Moisture Content of the Soil
1.1.3 NEED AND SCOPE OF THE EXPERIMENT
Moisture content is commonly used in geotechnical engineering practice. The knowledge of the natural moisture content is essential in determining the bearing capacity and settlement and also in the analysis of stability of slopes and embankments. The behavior of a soil is often related to the amount of water in the …show more content…
S = = 1.5
The degree of saturation (S) is a measure of the void volume that is filled by water, expressed as a percentage ranging from 0 to 100. For a dry soil S = 0% whereas for a saturated soil S = 100% and for partially saturated soil, S varies between 0% and 100%. Soils below the water table are often saturated. The void ratio, porosity and degree of saturation indicate the relative proportions of air, water and solid present in a soil mass. Their values cannot be determined directly by means of a soil test.
