what is the diffrence of opc and ppc cement ? expailn
Answer Posted / 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.
