Silt Content Test For Sand - Civil Lead

It is the simple test to find out the silt content in sand. Fine material less than 150 Micron size found in the sand is called Silt. Excessive quantities of silt in the sand not only reduce bonding between cement and aggregate but also increase water demand, thereby reducing the strength of concrete.
