WebThe liquid and plastic limits are both dependent on the amount and type of clay in a soil, but the plasticity index is generally only dependent on the amount of clay present. It indicates the fineness of the soil and its characteristics as regards plasticity and cohesiveness, i.e., its power to change shape without altering its volume. WebThe plasticity index and the percentage finer than 2- μm particle size can be used to determine its activity number. The liquid limit of a soil containing substantial amounts of organic matter decreases dramatically when the soil is oven-dried before testing. ghostly voice at queens funeral

The values of these limits are used in a number of ways. There is also a close relationship between the limits and properties of a soil such as compressibility, permeability, and strength. This is thought to be very useful because as limit determination is relatively simple, it is more difficult to determine these other properties. Thus the Atterberg limits are not only used to identify the soil's classification, but it allows for the use of empirical correlations for some other engineering … WebNov 14, 2024 · 29K views 2 years ago chapter 34 - Plasticity index of Soil Plastic Index ( PI or Ip ) of soil is defined as the difference between the numerical value of liquid limit and …
