SUBJECT
Particle size distribution analysis or mechanical analysis is carried out in two systems: Sieve Analysis, Sedimentation Analysis. In Coarse Grained Soil : we study Gravel & Sand and In Fine Grained Soil: we study Silt & Clay.
Test of unit weight of soil can be determined using the following methods: Water Displacement Method, Submerged Mass Density Method, Core Cutter Method, Sand Replacement Method.
Test of specific gravity can be computed using 50 ml density bottle,500ml flask or pycnometer. Density bottle method is accurate & suitable for all soil.
Interrelationship Between Voids ratio (e), Water Content (w), Specific Gravity (G), Degree of Saturation(s), Dry Unit Weight ,Unit Weight of Water, etc
