The water content, in percent, of the soil at the arbitrarily defined
boundary between liquid and plastic states is known as the ___.
Ans: Liquid Limit (LL)
The water content, in percent, of a soil at the boundary between the
plastic and semi-solid states is known as the ___.
Ans: Plastic Limit (PL)
The ___ is calculated as the difference between the liquid limit and the
plastic limit. The equation is as follows:
___ = __ - ___.
Ans: Plasticity index;
PI = LL - PL
Originally there were six "limits of consistency" of fine-grained soils.
Now LL, PL, and in some references, the shrinkage limit is known as
the ____.
Ans: Atterberg limits
The Plastic Limit "hand method" requires placing a mass of soil on a
glass plate, then - with your fingers - roll it into a ___ in diameter.
