Standard Test Method for Sand Equivalent Value of Soils

5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike or clay size fines in an aggregate. 5.3 This test method provides a rapid field method for determining changes in the quality of aggregates during production or placement.

Sand equivalent test Wikipedia

A higher sand equivalent value indicates that there is less clay‐like material in a sample. During the test, material from the test specimen that can pass through a No. 4 sieve is mixed with solutions of calcium chloride, formaldehyde and glycerin in a cylinder. The content is then left for sedimentation.

Sand Equivalents Quality in California

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 Test Vs Silt Content Test Concrete

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 concrete strength by more water demand. Is SE value of
