Sand Equivalent Test Method Explained and The Process ...

Sand Equivalent Solutions: Stock Solution is a concentrated mixture of calcium chloride in glycerin and is added to distilled water when preparing the working solution used in the test method. One gallon (3.8L) of the stock solution makes over 44 gallons of working solution. Because the blend is an ideal medium for fungal growth, a bioicide such as formaldehyde or glutaraldehyde is generally ...

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

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.
