## Specific Gravity | Properties of Soil | Soil Mechanics

Specific Gravity is the ratio of the weight of a given volume to the weight of standard fluid (water) of the same volume. It is represented as ‘G’. It is the Unit less. There are two types of specific gravity: True/Absolute Specific Gravity and Mass/Bulk/Apparent Specific Gravity

## Unit Weight and Density | Properties of Soil | Soil Mechanics

Unit Weight is the ratio of weight to volume. It is also known as the specific weight. And Density is the ratio of Mass to volume.

## Degree of Saturation, Air Content and Percentage Air Voids | Properties of Soil | Soil Mechanics

Degree of Saturation is defined as the ratio of the volume of water to the volume of voids present in a given soil mass. It is represented as ‘s’.

## Void Ratio and Porosity of Soil | Properties of Soil | Soil Mechanics

Void Ratio is defined as the ratio of the volume of voids (Vv) to the volume of solids(Vs) present in a given soil mass. It is represented as 'e'. Porosity (η): It is defined as the ratio of the volume of voids(Vv) to the volume of soil (V) present in the given soil mass. It is represented as 'η'.

## Soil Water & Types of Soil Water | Properties of Soil | Soil Mechanics

Water present in the soil in any form is termed soil water. Many types of sοil water: Ground (Free, Gravity) water, Capillary water, Structural water, and Adsorbed water.

## Determination of Water Content of Soil | Properties of Soil | Soil Mechanics

The various techniques for determining the water content of soil are as follows: Oven Drying Method, Sand Bath Method, Alcohol Method, Pycnometer Method, Calcium Carbide or Moisture Meter Method, Radiation Method, and Torsional Balance Method.

## Water Content or Moisture Content | Properties of Soil | Soil Mechanics

Water content (w):It is define as the weight of water to the weight of solids present in the given soil mass. Moisture content (m): It is define as the mass of water to the mass of solids present in the given soil mass. The  result of water content & moisture content are same .

## Phase Diagram of Soil | Properties of Soil | Soil Mechanics

Soil is a three-phase system that consists of solid, liquid & gaseous matter, that do not occupy separate spaces, but are blended with each other in a definite proportion, which in turn governs the properties 0f soil.

## Types of Soil | Properties of Soil | Soil Mechanics

There are many types of soil. Examples - Alluvial soil, Lacustrine soil, Marine soil, Aeolian soil, Glacial soil, Colluvial soil, Loess soil, Marl soil & others.

## Formation of Soil | Properties of Soil | Soil Mechanics

The process of formation of soil is termed as PEDOGENESIS. Soil is formed due to the weathering (erosion /wear and tear) of rocks. Weathering of rock can occur either physically or chemically.
