Both OPC & ppc are used in concrete.but the usage depends on the strength of the concrete that we should achieve. Generally for low strength concrete that is up to 25Kn/ m2 we use ppc and higher the concrete strength we use OPC
OPC is used for Concrete structure/also for masonry works
also/ But PPc can only used for Masonry works not fit to
use concrete structures. PPC is low heat of hydration no 1
for block/brick works/plastering/flooring works.
ppc or pozzolana portland has low heat of hydration as
compared , it produces less cracks on setting than opc or
ordinary portland cement . ppc is thus preferred
