  Standard Test Method for Sand Equivalent

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

  A CBR value of 2% is usually found for clay, highquality subbase will have CBR values between 80% and , and some sands may have values around 10%. The CBR testing can be applied to soils with a maximum particle size of 20 mm. For soils with bigger particles, other types of bearing capacity can be used like the Plate Bearing Test.

  Sand Equivalent Test Vs Silt Content Test

  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

  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.

  Some sources quote a much higher Rvalue 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 FOR 8 INCHES of thickness. That''s equivalent to an Rvalue of R per inch, but without considering moisture level. But really, the insulating value of earth

  However, the test can give rise to false negatives, whereby sand with low SE values produces concrete with acceptable performance. Conversely, sand with a high SE value can produce concrete with poor performance. The SE test relies on apparent density differences between ''good'' sand and ''bad'' clay. Although a flocculant is used to encourage separation of fine clay particles, similar

  Sand Equivalent Value Soil testing engineering

  · If we see the sand equivalent formula, which is 100*sand reading/ clay reading, the higher the sand reading during testing means it gives higher sand equivalent value, and that means there are less clayey materials.

  Sand equivalent test Wikipedia

  The sand equivalent test quantifies the relative abundance of sand versus clay in soil. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. 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
