Ordinary Portland Cement (OPC) [or other cementitious materials] has a property of hydraulic setting, binding and hardening when mixed with water. Some materials undergo hydraulic setting when combined with water in presence of cements, but not by itself.PC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and hig â¦ h reactive silica. High reactive silica improves the quality of cement by reducing liberated lime. + 28 others found this useful.
