Test for Silt Content in Sand – theconstructor
Percentage 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. Observation table
