Calculate the sand equivalent using the following equation: Where: sand reading = height of sand in cylinder (mm) clay reading = height of clay in cylinder (mm) The sand equivalent value should be reported to the nearest higher whole number. For example, if the SE equation gives SE = 38.25, the reported SE should be 39.

sand reading clay reading • 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%.
SE - The sand equivalent value. LD - The loss by Decantation given as a percentage. P -The decimal fraction of the minus no. 200 mesh material in a sample of sand. A -The sand reading in inches in the sand equivalent test. K -The ratio of the clay reading minus the sand reading and the sand reading in the sand equivalent test. c -y· K
Aug 11, 2011· What is the difference between sand equivalent test values and sa simple silt content test? I mean when you finish a SE test, specs say that min 75% SE value is accepatable, which means max 25% of clay/silt content is acceptable limit for sand used in structural concrete! But other specs say silt content more than 8% in sand would ruin the ...

Some sources quote a much higher R-value for sand and gravel aggregate but you need to look at the thickness or amount of sand or gravel when you see such quots. For example some cite sand and gravel aggregate as providing R 1.11 FOR 8 INCHES of thickness. That's equivalent to an R-value of R 0.1388 per inch, but without considering moisture level.
