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.

Use 2.5 mm (0.1 in.) as the smallest unit for the readings and always use the higher graduation if the readings fall between one-tenth inch marks. Calculate the sand equivalent to the nearest 0.1% using the following formula: SE= (Sand Reading/Clay Reading)* Cleaner aggregates will have a higher SE value.
