PPC cement has good compressive strength that can reach 13MPa in 3 days, 22 MPa in 7 days, and 33 MPa in 28 days. The hydration rate and hydration heat of PPC cement are low, which is related to the variety and quantity of mixed materials. PPC cement has a high resistance to sulfate attack in acid water and carbonic acid environment.Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC grade.Review on vertical roller mill in cement industry & its performance ...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.
