What is the disadvantage of OPC over PPC in a slab

OPC and PPC are two different forms of cement. Ordinary Portland Cement (OPC) is the most widely used in construction. It consists of limestone and other materials like argillaceous, calcareous, and gypsum. On the other hand, Portland Pozzolana Cement (PPC) is a combination of volcanic ash, calcined clay or silica fumes, and fly ash which is around 15%-35% of cement weight.
