WebThe soil having activity between 0.25 to 1.25 is called normal soil. 6) Thixotropy of soil The phenomena in which the clays change their strength either by strength loss or strength gain with respect to time without … 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 prope… WebIn Figure 1, the flow index is defined as the slope of the flow curve.
