The hydraulic cementitious materials made of Portland cement clinker, pozzolanic material, and a proper amount of gypsum are all called Portland pozzolana cement (PPC cement). It is a kind of blended cement which is manufactured by mixing and fine-grinding silicate cement clinker, pozzolanic material, and gypsum.

Pozzolana has silica content that makes it cheaper and therefore reduces the cost of cement. Pozzolana cement has a very good resistance against sulfate attack hence it is used in hydraulic structures, marine structures, seashore structures, dam structures, etc. PPC is used in prestressed concrete and post-stressed concrete members.

Once the pozzolana has been ground, it must be blended with lime and/or OPC to produce a pozzolanic cement. This can be accomplished by human or animal-powered methods but full homogeneity is unlikely to be achieved and the strength and consistency of cements blended in this manner will be variable. ... preferably intergrinding in a ball mill ...
