differentiate the types of clay minerals according to their level of plasticity

Soil classification - Faculty of Environment and …

Clay minerals are produced mainly from the chemical weathering and decomposition of feldspars, such as orthoclase and plagioclase, and some micas. They are small in size and very flaky in shape. The key to some of the properties of clay soils, e.g. plasticity, compressibility, swelling/shrinkage potential, lies in the structure of clay minerals.

Difference Between Silt and Clay -

What is the difference between Silt and Clay? Though silt and clay are classified as fine soils, they have some difference between them. – Clay particles are much lesser in size than silt particles, even though all soils with particles size less than 0.075mm are classified as either silt or clay.

What is Plasticity in Clay? -

A pure clay (of which there are said to be around 30 types) is one that is not made of any other materials; a clay body is made up many different clay materials like kaolin or grog. There are hundreds of types of clay bodies, as there are so many different types of combinations of clay minerals.

Effects of Soil and Air Drying Methods on Soil Plasticity ...

Atterberg Limits were initially defined in 1911, by Albert Atterberg, a Swedish scientist. Their purposes are to classifying cohesive soils and determine engineering properties of soils. According to ASTM, all the soils tested by Atterberg limits should be oven dried, it is because drying the soils in different degree will alter their properties significantly.
