The new plasticity chart is of great significance as it allows soil classification to be performed without thread-rolling tests, which may well introduce the operator's influence. bizzare leprous shop

"WebThe liquid limit of a soil is the water content at which the soil behaves practically like a liquid, but has small shear strength. It flows to close the groove in just 25 blows in Casagrande’s liquid limit device.

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… WebPlasticity Index Flow index Toughness Index Liquidity Index Consistency Index Soil MechanicsThis is another video which brings you yet another "Soil ...
