Sand Equivalents
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.
Demonstrating the Worth of Recycled Aggregates—A …
The EW failed the Sand Equivalent test even when 20% dune sand was added. Limestone from most of the quarries in Qatar also failed this test (Salim Kutty, personal communication, January 30, 2014).
