Answer / sagar sontakke

No,Aggregate size is indipendent of concrete grade.we can
use still higher size of aggregate.aggregate size is
depending on the minimum cover & spacing of reinforcement
in the structures like beam,retaining wall,column etc.This
is so because aggregate should pass through the two bars.
