Sand Equivalent Test Vs Silt Content Test - Concrete Durability

Sand Equivalent Test Vs Silt Content Test - Concrete Durability

Sand Equivalent Test Vs Silt Content Test - Concrete Durability

(OP)
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 more than 8% in sand would ruin the concrete strength by more water demand.

Is SE value of 75% min is a reasonable value for sand to be used in concrete?

In silt content test we just add salt solution to sand until its immersed and keep it undistrubed for 3 hrs. Silt height & sand height is then read. Silt Content = Silt ht/ Sand ht x100.

Please comment
