Minimum Sand Equivalent In Concrete

Apr 30, 2011 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.
