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.
