  • 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 .

  • Sand Equivalent Value

    30/06/2009 · 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. Either clay content should be calculated as 100sand equivalent value to set minimum requirement as above or if we use sand equivalent, what the Spe'c should set is a .
