Grading & Plasticity: % Passing, D10/D30/D60 on a Log Scale, Cu & Cc, the Liquid Limit and a Plasticity Term
This lesson is part of the course
In this lesson
You turn a sieve analysis into % passing, interpolate D10, D30 and D60 on a log size scale, compute Cu and Cc, fit the liquid limit at 25 blows and look up a plasticity term in a fictional chart.
