PPC is a special blended
cement as per BIS specification, IS: 1489, and is produced by inter-grinding
Ordinary Portland Cement clinker with high quality processed fly ash along with
gypsum. Due to its inherent characteristics, PPC aids in creating corrosion
resistant concrete that is far superior to concrete made with OPC. The use of
blended cement in concrete reduces crack formation, improves workability,
inhibits sulphate attacks and reduces the heat of hydration. Moreover, its 28
days strength proves to be much better than OPC 53 Grade.
