What is PPC Cement?

Where Can You Use PPC Cement?
Before you purchase PPC cement, you should know where it can be applied in the best manner. Here is a list of the best use case scenarios for PPC cement.- PPC cement is excellent for construction works that require impermeability. It is ideal for underground, wet concrete works, water systems, resistance to freshwater, and sulfate corrosion. PPC cement is extensively used in hydraulic systems, marine structures, water dams, construction in offshore locations, water disposal systems, etc.
- Like OPC cement, PPC cement is acceptable in general engineering works, including mass-concrete construction.
- PPC cement is necessary to create smooth surface finishes for decoration for aesthetic purposes.
- As PPC cement is cheaper, it is considered by many property owners who want to save some cost without losing any strength of the building.
- PPC cement is recommended for brick masonry, plastering, tiling, and waterproofing.
General Properties of PPC Cement
Here is a list of a few important properties of PPC cement:The initial setting time is: | 30 minutes (minimum) |
The final setting time is: | 10 hours (maximum) |
Strength achieved at three days: | 13 MPa (minimum) |
Strength achieved at seven days: | 22 MPa (minimum) |
Strength achieved at 28 days: | 33 MPa (minimum) |
Advantages of Using PPC cement in Your Construction Project
Generally, different types of cement are used in construction projects to maximize its durability and efficiency. Using good quality PPC cement can save costs and provide greater value to the environment. Here are some significant advantages of using PPC cement:- PPC cement is considered an Eco-Friendly cement because it utilizes the ingredients produced as waste or by-products in coal power plants. Using renewable and recycled waste makes PPC the first choice for many environmentally conscious individuals.
- PPC cement has a very fine powdery form that makes it an excellent choice for plastering.
- PPC cement consumes Calcium Hydroxide and does not produce it like OPC cement.
- PPC cement produces heat of hydration at a lower rate.
- Due to finer form compared to OPC cement, PPC cement has improved pore size distribution that helps to reduce the micro-cracks at transition zones.
- Portland Pozzolana Cement consists of silica material that makes it cheaper than other alternatives. Hence, the production cost of PPC is reduced, making it an economical option for many property owners.
- PPC cement has a very high resistance to sulfate attacks, making it ideal for specific structures like buildings along the seashore and other scenarios where structures are vulnerable to sulfate attacks.
- PPC cement can be easily used in prestressed and post-stressed concrete members.
- PPC cement reduces its carbon footprint further by eliminating carbon monoxide from concrete, a greenhouse gas, allowing the environment to be safer.
- Using PPC cement increases the toughness and durability of concrete. Pozzolana materials are very fine, allowing them to fill the holes between the reinforcement and aggregate, which decreases the shrinkage of structure and minimizes the formation of honeycombs, resulting in a reduced leakage.
Some Disadvantages of PPC Cement
Despite many advantages, PPC has some disadvantages that you should be aware of.- PPC cement has a lower rate of strength development initially compared to OPC.
- PPC cement has lower corrosion resistance to corrosion of steel reinforcement.
- The setting time of PPC cement is usually longer than other alternatives.
