Zone-I represents the coarse sand and zone-IV represents the finer sand in all the four zones.

These specifications do not specify any limit for fineness modulus to be used in concrete. It divides the sand in four zones i.e. from Zone I to Zone IV. Zone I"Sand being very coarse and Zone 4 sand is very fine. It is generally recommended by code to use sands of zones I to Zone III for Structural concrete works.

Zone I - Coarse Sand.
Zone II - Normal Sand.
Zone III - Fine Sand.
Zone IV - Very Fine Sand.

Why zone 1 is coarse. Max w/c ratio is max for zone 1.
