Silt Content Test for Sand (Fine Aggregate) - Civilology

Test Procedure. First, we have to fill the measuring cylinder with 1% solution of salt and water up to 50 ml. Add sand to it until the level reaches 100 ml. Then fill the solution up to 150 ml level. Cover the cylinder and shake it well (as shown in video); After 3 hours, the silt content settled down over the sand layer; Now note.
