  Portland Pozzolana Cement (PPC) Introduction Portland Pozzolana Cement (PPC) is one of the most widely used types of cement in modern construction. It is known for its durability, eco-friendliness, and long-term strength development. PPC is a blended cement made by combining Ordinary Portland Cement (OPC) clinker with pozzolanic materials such as fly ash, volcanic ash, or calcined clay along with gypsum. This combination improves the performance of concrete, making it stronger, denser, and more resistant to environmental damage over time. What is PPC Cement? PPC stands for Portland Pozzolana Cement . It is a type of blended cement produced by grinding OPC clinker with pozzolanic materials and gypsum. Typically, PPC contains: 15%–35% pozzolanic material (like fly ash) Remaining clinker and gypsum The pozzolanic materials do not have cementing properties on their own, but they react with calcium hydroxide released during cement hydration to form additional binding com...
