Sand Equivalent Value

Jun 30, 2009· Either clay content should be calculated as 100-sand equivalent value to set minimum requirement as above or if we use sand equivalent, what the Spe'c should set is a maximum requirement I read AASHTO and found that it has similar requirement to our specification.

Sand Equivalents

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.
