Now, 40 tons of load is applied to the test cylinder in 10 minutes. We know, 40 ton= 40000 kg= 400 KN. Therefore, 400 KN of the load should be applied. The time(10 minutes) is started in the stopwatch. The crushed material is then transferred into the sieve of size 2.36 mm.

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.
