[email protected]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!.
A representative of 10 sand samples were collected from different pits and rivers for geotechnical characterizations at the national civil engineering laboratory (labogenie) located in yaound, cameroon.The tests included the sand equivalent test (e s) and the fineness modulus (m f).Sand quarries were also described with details of the.
