Equivalent Sand - an overview ScienceDirect Topics

The sand equivalent test is used to limit the presence of clay material in the aggregate. The sand equivalent test (AASHTO T176; ASTM D2419) is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils).

Sand Equivalents - Quality in California

2011-4-30  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.

Sand Equivalent Value of Soils and Fine Aggregate

2020-1-25  If the calculated sand equivalent is not a whole number, report it as the next higher whole number. Higher sand equivalent values indicate “cleaner” (less fine dust or clay-like materials) aggregate. Typical sand equivalent values range from less than 30% to more than 90%.
