OPC vs. PPC Cement: What's the Difference? Choosing the right type of cement is key for any construction project. Two common options are Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC). They have different properties, costs, and uses. This guide will help you understand the main differences between OPC and PPC cement. Raw Materials OPC : Made from limestone, silica, and alumina. PPC : Made from a mix of OPC and pozzolanic materials. These materials include fly ash, volcanic ash, or burnt clay. Curing Time OPC : Cures faster than PPC. It can reach its full strength in about 28 days. PPC : Takes longer to gain its full strength. Curing time is important because it affects how quickly you can move forward with construction.  The minimum curing time for Ordinary Portland Cement (OPC) is 7 days, while for Portland Pozzolana Cement (PPC), it's 10 days. However, this can increase to 10 days for OPC and 14 days for PPC in hot and dry weather conditions. Cost PPC: Gen...
