PPC= OPC43 Grade + 30-35% (either calcinated clay or Pozzolona)=> OPC 33 grade

so PPC has no grade that is equivalant to OPC 33.

When we add fly ash to make PPC then its strength is not fixed.
More you do curing more you get strength, moment you stop curing strength will stop that place. Where as in OPC highest strength is fixed to a mark. that is why OPC has grading but PPC dosen't have.
