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 Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE On the flip side it is not uncommon to see a 1/4" x .

2009-06-30· If we see the sand equivalent formula, which is 100*sand reading/ clay reading, the higher the sand reading during testing means it gives higher sand equivalent value, and that means there are less clayey materials Either clay content should be calculated as 100-sand equivalent value to set minimum requirement as above or if we use sand equivalent, what the Spe'c should set is a maximum .
