Classification of Soil.
The purpose of the classification of soil is to arrange various types of soils into groups according to their engineering or agricultural properties and various other characteristics.Soil possessing similar characteristics can be placed in the same group.Soil survey and soil classification are carried out by several agencies...
Sieve analysis of soil is a simple operation of dividing a sample of aggregate into fractions, each consisting of particles of the same size.
Sieve Analysis of Soil.
Theory.
In practice, each fraction contains particles between definite limits, these being the openings of standard test sieves.Before sieving, the soil should be air...
Determination of Field Density Test of Soil by Sand Replacement Method.
The field density test of soil is conducted in the field to know whether the specified compaction is achieved or not. Normally Sand Replacement Method is adopted for this purpose.Sand Replacement Method is also known as Sand Cone Method.The...
Atterberg Limits.
In 1911, the Swedish agriculturist Atterberg divided the entire range of soil state (from liquid to solid state) into four stages, which is known as Atterberg Limits or Consistency Limits.1. The liquid state,2. The plastic state,3. The semi-solid state, and4. The solid state.He set arbitrary limits, known as...

Standard Penetration Test
The Standard Penetration Test (SPT) is most popular and economical test to determine the surface information, both on land and offshore. This test is widely used to obtain the bearing capacity of soil.

In nature, there are different types of rocks available, i.e., rocks are classified into three categories, Geologically, chemically, and structurally.
(1) Geological Types of Rocks.
This classification is based on the mode or process of formation of a rock. Thus, some rocks may be formed from natural hot molten materials.Others may...
Sand is an important construction material of natural origin, mixed with cement and lime, millions of tons of sands are used every month for construction as mortars, plasters, and concrete.The term sand is used for rock particles that range in grain size between 2 mm and 1/16 mm. In...
