Is OPC cement better than PPC?
By Emma Martin
Is OPC cement better than PPC?
PPC has an edge on OPC as PPC has slower rate of heat of hydration. Thereby PPC is prone to less cracks & reduced shrinkage), better workability and finishing (as fly ash based cement are spherical in shape and finer in size).
Which is better OPC 43 or PPC?
OPC is better when you need to cast a slab in a rainy season. OPC (m53) attains strength in a shorter time, while PPC (m43) takes longer. Faster is the drying process, more is the risk of cracking of cement, and therefore it need more care and more amount of water for curing in a lesser time.
Which is better OPC or PCC?
PCC gives comparable strength and durability like OPC. The basic difference between them is in the manufacturing technology. Only 65% to 80% of clinker is required to produce PCC while 95% of clinker is required to produce OPC. As a result, PCC is gaining popularity worldwide due to its environmental significance.
What is the basic difference between OPC and PPC?
The initial strength is less but for longer duration, the strength of PPC is comparatively higher than OPC. OPC generates more heat after mixing with the water which makes OPC is not suitable for mass casting. PPC has a slow hydration process due to which heat generation is comparatively lower.

Which company OPC cement is best?
Best OPC 53 grade Cement in India:- in india, several cement company and manufacturers which provide best OPC 53 grade Cement are ACC f2r superfast, ACC gold water shield, lafarge concreto, Ambuja Plus are most popular, most preferred and best quality Cement in India.
Which cement is costly OPC or PPC?
Cost. The cost of OPC is around 300 rupees per bag which is slightly more expensive than PPC. Whereas in the case of PPC, the expensive clinker is replaced by pozzolanic Material such as fly ash hence the price of PPC is slightly less than who OPC. Generally, there is a price difference of approximately 5 rupees.
Which cement is cheaper OPC or PPC?
Portland Pozzolana Cement is a variation of Ordinary Portland Cement. Pozzolana materials namely fly ash, volcanic ash, are added to the OPC so that it becomes PPC. Pozzolana materials are added to the cement in the ratio of 15% to 35% by weight. PPC is cheaper than OPC.
Which is best PPC cement?
Bhavya Portland Pozzolana Cement, Packaging Size: 50kg. ₹ 350 / Piece.
How is PPC cement used?
Uses of Portland Pozzolana Cement
- Used in hydraulic structures, marine structures, construction near the sea shore, dam construction etc.
- Used in pre-stressed and post-tensioned concrete members.
- Used in masonry mortars and plastering.
- As it gives better surface finish, it is used in decorative and art structures.
What’s the difference between ordinary portland cement and PPC?
OPC is ideal for the construction of residential and industrial complexes. Both OPC and PPC are commonly used cements in construction. Now a days, PPC is used as a substitute of Ordinary Portland Cement (OPC Cement). Since PPC contains pozzolanic materials, it helps to enhance the strength of concrete.
Which is better OPC 53 or PPC 53 grade cement?
Since it gains early strength and has cost saving advantages as discussed above, OPC 53 Grade cement is generally recommended for Structural Concrete or Reinforced Concrete Works (like Columns, Beams, Slab etc.,) On the other hand, PPC (Portland Pozzolana Cement) is made up of 75 – 77% cement clinker, 20% flyash and 3-5% gypsum.
Which is better for wall tiles, OPC or PPC?
Gypsum is as an additive to increase the setting time of the cement to a workable 30 minutes or more. OPC Cement gives high compressive strength at early ages and at 28 days. A 53 Grade cement gives up to 70 MPa strength against a minimum 53 MPa specified by BIS.
Which is better for the environment PPC or OPC?
Both PPC and OPC cements are ecofriendly. But PPC employs natural and industrial waste which reduces the environment pollution. In OPC cement there are 3 grades available and the strength of PPC matches OPC 33 after the process of curing.
What’s the difference between OPC and PPC cement?
OPC is produced by grinding limestone and secondary materials to fine powder. Compared to PPC, OPC usually takes little time for setting, which is important for large scale constructions, thus speeding up the process of determining the length of the construction period.
What are the different grades of Portland cement?
OPC Cement or Ordinary Portland Cement (OPC) is manufactured by grinding a mixture of limestone and other raw materials like argillaceous, calcareous, gypsum to a powder. This cement is available in three types of grades, such as OPC 33 grade, OPC 43 grade and OPC 53 grade.
What kind of cement is OPC 53 grade?
OPC 53 Grade Cement: OPC (Ordinary Portland Cement) is the basic form of cement with 95% cement clinkers and 5% being gypsum. Gypsum is as an additive to increase the setting time of the cement to a workable 30 minutes or more.
Which is stronger Portland pozzolana or PPC cement?
In 28 days PPC achieve compressive strength of 56.5 N/mm 2. From the above data we can conclude that initial strength of OPC cement is higher than PPC cement. But for long term strength , Portland Pozzolana Cement is higher than Ordinary Portland Cement.
