For engineering purpose, soil can be classified in terms of___________
For general engineering purposes, soil can be classified in terms of
particle size, textural and unified soil.
Systems which are used for classification of soil based on particle size are__________
Based on particle size, soil can be classified as
1) U.S. Bureau of soil and public road administration system
2) The M.I.T. classification system
3) Indian standard classification system
4) International soil classification system.
In particle size classification system ,the soils are classified according to__________
In the particle soil classification system, soils are arranged to the grain size.
Which of the following terms are used to indicate grain sizes?
Terms such as gravel, sand, silt, and clay are used to indicate grain sizes .these terms are used only as designation of particle size.
The term ‘silt’ in particle size classification system ,can be replaced by___________
As the system is classified based on size, it is preferable to use the word ‘silt size’ and ‘clay size’ in place of simply ‘silt’ or ‘clay’.
Indian standard classification of soil is based on_________
Indian standard classification (IS: 1948-1970) is based on the M.I.T. system.
Soil occurring in nature, is composed of__________
Soil occurring in nature is composed of different percentage of sand, silt, and clay size particles.
The purpose of soil classification is to___________
The purpose of soil classification is to arrange various types of soils in to groups according to their engineering or agricultural properties.
Particle size classification is best suited for_________
Since properties of clay soils is less dependent on particle size distrubution(textural classification) and more dependent on size it is best suited for clay soil.
Particle size classification system does not signify__________
Particle size classification used only as designation of particle sizes, and do not signify the naturally occurring types which are mixtures of particle of different sizes.
