Excessive quantity of silt, not only reduces the bonding of cement and fine aggregates but also affects the strength and durability of work. You can check out this article for silt and clay properties. In the field, we have to conduct silt test for every 20 Cum of sand. This may vary.

IS-2386-Part-III-1963 describes various procedures to find out the specific gravity of aggregates of different sizes. Here the method applicable to aggregates larger than 10 mm in size has been described as follows ― A sample of aggregate not less than 2 kg in weight is taken and washed thoroughly to remove dust, and silt particles etc.

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.
