Which is better for use in slabs : PPC/PSC or OPC ? Quora
Portland Pozzolana Cement (PPC) is a variation of OPC which includes a mixture of a pozzolanic material which can increase the strength of the concrete and reduce the amount of OPC used. OPC is produced simply by grinding to a powder limestone and secondary materials; PPC is the result of adding pozzolana or similar materials such as volcanic ash, clay, slag, silica, fume, fly ash, or shale with OPC.
