Direction: Laboratory sieve analysis was carried out on a soil sample using a complete set of standard IS sieves. Out of 500g of soil used in the test, 200g was retained on IS 600μ sieve, 250g was retained on IS 500μ sieve and the remaining 50g was retained on IS 425μ sieve.

The classification of the soil is
-
- SP
- SW
- GP
- GW
Correct Option: B
600 μ = 600 × 10–6 m = .6 × 10–3 m = .6 mm
Similarly 500 μ = 0.5 m
Maximum amount of soil is of size between 0.5 and 0.6
So it is sand.
∵ Cu > 6, it is graded.
∴ it is S
