Which is better OPC or PPC or PSC?
OPC takes lesser time to set than PPC. If you are construction near seashore areas, PSC must be chosen over PPC and OPC because of its excellent corrosion resistance properties.
What is the setting time of OPC and PPC cement?
The initial setting time of OPC and PPC is the same and it is 30 minutes whereas the final setting time of OPC is 280 minutes that is 11.67 days it’s setting time is less than PPC so it is recommended in the project where props are to be removed early.
What is the difference between OPC and PSC?
OPC 53 Grade means the minimum compressive strength requirement is 53 MPa at 28 days. PSC or Portland Slag cement is a kind of blended cement manufactured by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement.
What is difference between PPC and PSC cement?
Portland Slag Cement, commonly known as PSC, is blended cement. Portland Pozzolana Cement, also known as (PPC) on the other hand is created of Pozzolans which are siliceous material that can be added to concrete mixtures, potentially lower the mix cost without harming the performance characteristics.
Why Portland slag cement is used?
Portland slag cement is nowadays commonly used in general civil engineering construction works and is mainly preferred for construction of main structures and in coastal areas where excessive amount of chloride and sulphate are present. It is most useful in massive construction projects such as dams.

Which sets faster OPC or PPC?
Its faster setting time helps faster construction. Setting time of PPC us higher than OPC. Its initial setting time is 30 minutes and final setting time is 600 minutes. Its slower setting time helps to get better finishing.
What is OPC PPC and PSC cement?
At this temperature clinker is formed which on cooling is ground with gypsum to obtain OPC Cement (Ordinary Portland Cement). If at the time of grinding, fly ash or Slag is added then we get PPC Cement (Portland Pozzolana Cement) or PSC Cement (Portland Slag Cement) respectively.

Its initial setting time is 30 minutes and final setting time is 600 minutes. Its slower setting time helps to get better finishing.
What is the difference between OPC and PPC in construction?
For example RCC casting of buildings, mass concreting for bridges and even plastering and other non-structural works. Lower than PPC. Its initial setting time is 30 minutes and final setting time is 280 minutes. Its faster setting time helps faster construction. Setting time of PPC us higher than OPC.
What are the advantages and disadvantages of OPC?
Advantages Of OPC (Ordinary Portland Cement) 1 Higher initial strength compared to PPC 2 Shorter curing period and as a result low curing costs. 3 OPC has shorter setting time compared to PPC. 4 It has great resistance to cracking and shrinkage but less resistant to chemical attacks.
What is the difference between PPC and RCC casting?
For example RCC casting of buildings, mass concreting for bridges and even plastering and other non-structural works. Lower than PPC. Its initial setting time is 30 minutes and final setting time is 280 minutes. Its faster setting time helps faster construction.
