Soil Texture Lesson and Activity - … 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 …
WebJul 7, 2015 · The Colloidal “Activity” of Clays. In any particular clay stratum the ratio of the plasticity index to the clay fraction content is approximately constant, and may be defined as the “activity” of the clay.
