Sand Equivalent Test Vs Silt Content Test - Concrete Durability .

Hi, 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.
