Portland Pozzolana cement is an incorporated cement produced in that certain ratio by the synthesis and characterization of OPC cement from pozzolana materials.It's also generally referred to as PPC cement. PPC type cement is a form of Portland cement distinguished by the existence of pozzolana particles such as fly powder, volcanic ash, that is applied to OPC by 15percent to 35%.
Down-grinding at a fixed depth of cut (a p = 0.1 mm) is chosen in all the grinding trials.The wheel speed v s is varied from 20 to 140 m/s, and the workpiece infeed speed v w is ranged from 120 to 300 mm/min. Particularly, the wheel speeds of 20 and 50 m/s are chosen for the conventional speed grinding, while those of 80, 100, 120 and 140 m/s are applied for high speed grinding.

There are three main grinding processes in the cement production: raw meal grinding, cement grinding, and raw coal grinding.
PPC Cement is manufactured by grinding the OPC clinker with 10 to 25 percent of the pozzolanic material. As per the recent standards of manufacturing, it is about 35%. Pozzolana materials may be natural or artificial that have silica in them in a reactive form. PPC Cement also contains OPC clinker and gypsum along with pozzolanic materials.
