It takes some time to develop the strength. Strength developed over time is higher than the OPC. Heat of hydration and rise of the temperature of the concrete is higher than the PPC. Since the hydration process is lower, the heat of hydration is lower. The use of additives such as fly ash, silica fume, etc. is the main reason for this.

Portland Pozzolana Cement (PPC) is a cement made of pozzolanic substances such fly ash, rice husk ash, or volcanic ash and OPC. During the grinding stage, the OPC and pozzolanic components are blended together. Pozzolanic elements are added to cement to improve performance and sustainability. OPC cement sets up rather quickly, enabling …

Workability. PPC exhibits better workability than OPC, making it easier to handle and mix. It provides improved cohesion, reduced water demand, and enhanced resistance to segregation, resulting in smoother concrete surfaces. These properties make PPC well-suited for intricate architectural designs and decorative elements.
