What is the difference between OPC and PPC cement?
OPC (Ordinary Portland Cement) and PPC (Portland Pozzolana Cement) are two types of cement used in construction. The primary difference between them lies in their composition and properties. OPC is made from a mixture of limestone, clay, and other minerals, whereas PPC is made by grinding together pozzolana (usually fly ash) and clinker. This difference in composition affects their strength, durability, and resistance to chemical attacks.
The choice between OPC and PPC depends on the specific requirements of the construction project. OPC is generally stronger and more suitable for high-strength concrete applications, whereas PPC is more resistant to chemical attacks and is often used in marine and hydraulic structures.
