powerfull than ppc sychronising thier molecules as closer
it was only bares by the concreet only if ppc used for
concreeet it will reqire more water if not the pole may
have some holes ....

Answer / s k jha

PPC is widely used instead of OPC to avoid cracks developed
due to temperature variation.But, also to be noted that
setting time of PPC is more than OPC, therfore for
hydration and dehydration proces of concrete more and more
water is required.Since ppc takes more setting time
therfore internal molecules may colesces together to make a
firm bond between the particles and that is the reason
cracks not appears after proper curing.

Answer / ds raju

OPC is generally used for concrete where less quantity is
there in single pour.
PPC is generally used in mass concrete pours like
Dams,Heavy Equipment foundations, etc.
