Sand Equivalent Test Method Explained and The Process
When irrigating the sand equivalent sample, the working solution container must be positioned 36in (90cm) above the work surface. As with the stock solution, the purity of the working solution needs to be monitored over time and discarded if fungal growth occurs.

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, 2011So 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 TEST FOR CONTROL OF MATERIALS
it is concluded that the sand equivalent test is useful in detecting the presence of adverse amounts of clay in granular base materials. it may be used as a quick field test to control the amount of adverse clays in concrete sand. it may also be used to limit the amount of fine dust or clay that may exist as a coating on particles of mineral

whereas the sand equivalent results give an indication of amount and activity of the clay size fraction. A linking parameter was needed to draw a correlation between the two tests, and the liquid limit of the clay-size fraction was chosen. Fifteen samples of concrete sand from various locations in Texas were obtained.
