difference between plasticity inde and sand equivalent value

Sand Equivalents Quality in California

Apr 30, 2011 · The test results are a number but it is a percentage of good material in your sample. So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental. If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental.
