Nowadays, PPC is used as a substitute for ordinary Portland cement (OPC cement). Since PPC contains pozzolanic materials, it helps to enhance the strength of concrete. The quantity of PPC required in making the concrete is less when compared to OPC. PPC is a green material that contributes towards sustainable development.
PPC (Portland Pozzolana Cement) is a variant of OPC (Ordinary Portland Cement.) These two type of cement differs from each other in terms of component, strength, heat …
More expensive than PPC cement. Less expensive than OPC cement. Has a higher rate of shrinkage and is more prone to cracking. Has a lower rate of shrinkage and is less prone to cracking. Higher carbon footprint due to the higher amount of clinker used. Lower carbon footprint due to the use of fly ash as a pozzolanic material.

Using PPC eliminates surface cracks due to low heat of hydration. Setting time is slightly more than OPC, which gives PPC more workable time. Strength development continues even after 28 days, giving ultimate higher strength to the concreate. Our addition of Fly Ash improves particle size distribution and gives a perfect concrete matrix.

OPC cement also has increased workability and higher strength at later stages. Hence, it has early strength and also has cost saving advantages can generally used for the construction of concrete slab. OPC cement can also be recommended for the construction of columns, beams, etc. On the other hand, PPC cement is made up of 75-77% cement ...
Selection of proper type of cement and its qualitative aspects are important for the long-term durability of the home. The choice of type of cement depends on various other factors such as the cost of cement, and its availability in the local market. It also depends on the importance of structure, high performance of concrete, its purpose and anticipated use, …
The durability of OPC – It is less durable when compared to PPC cement. You can crumble it rather easily if it is not used as concrete. The durability of PPC – This is slightly more durable when compared to OPC. The motto of PPC is, after all, to enhance the durability of OPC cement. 4.
