More2 天前 Silt Layer Thickness = 1 cm. Sand + Silt Layer Height or Thickness = 10 cm. Silt Content of Sand = (1 cm / 10 cm) x 100 %. Silt Content of Sand = 1%. So, from the above Test and calculations, we can say that this sand has a 1% silt content. Silt content limit in sand as per IS code is 8%, so this sand we can use for construction purposes.

More2006-2-1 Silt (particles equal to or less than 75 micrometers [:m] in diameter) content is determined by measuring the portion of dry aggregate material that passes through a 200-mesh screen, using ASTM-C-136 method.1 Table 13.2.4-1 summarizes measured silt
MorePercentage of Silt Content = (V1/V2) x 100. V1 - Volume of silt layer. V2 - Volume of sand layer. For example, for a given sand sample, if V1 comes out to be 9 and V2 is 130, the % silt content would be 6.9 %. The permissible value of silt content in Sand is 8%, hence the sand sample is ok and can be used for construction purposes.
