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.
