What is PPC and OPC in cement?

OPC typically means Ordinary Portland Cement. This is standard concrete used for many purposes. PPC mean Pozzolanic Portland Cement. Pozzolans are siliceous material than can be added to concrete mixtures, potentially lower the mix cost without harming the performance characteristics.

Similarly, you may ask, what is difference between PPC and OPC cement?

Difference Between OPC Cement and PPC Cement. 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. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing.

Beside above, why is PPC cement better than OPC? 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).

Considering this, which is better OPC or PPC?

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. PPC on the other hand can attain strength equal to OPC, but takes a longer time.

What is PPC cement used for?

Portland Pozzolana Cement (PPC) It can be confidently employed in construction of hydraulic structures, marine works, mass concreting such as dams, dykes, retaining walls foundations and sewage pipes. It is also suitable for use in common applications such as masonry mortars and plastering.

Which cement is best for RCC?

OPC 53 Grade cement is recommended in all RCC structures like footing, column, beam and slabs, where ever initial and ultimate strength is the major structural requirement.

Can we use PPC Cement for RCC work?

PPC can be used for Concreting of Heavy RCC structures… there is no restriction on grades of concrete upto which it can be used.

Which cement is better 43 grade or 53 grade?

OPC 43 Grade cement attains a minimum compression strength of 43 MPa in 28 days of setting as compared to OPC 53 which attains a strenth of 53 MPa in the same time. Initial Strength: 53 Grade attains a minimum strength of 27 MPa in 3 days as compared to only 23 MPa achieved by 43 grade cement.

Can we mix OPC and PPC?

PPC is batched by blending OPC cement with pozzolonic material like Pulverised Fly Ash (PFA) at different proportions. In fact you are making concrete with cementetious material like fly ash or slag are more durable and environmentally better (eco friendly) as compare to concrete with only OPC.

Which cement is best for roof?

Which cement is better for RCC roof, PPC or PSC?

33 Grade Ordinary Portland Cement. This ordinary 'Portland' cement is used maximum in the country.
43 Grade Ordinary Portland Cement. 43 grades of cement are used where high early strength in 1 to 28 days range is required.
53 Grade Ordinary Portland Cement.

What is the advantage of PPC over OPC?

PPC has high durability than OPC which means the structure will last longer and have longer life. 04. PPC is more resistant towards the attack of sulphates, alkalies, chlorides and chemicals as compared to OPC.

Which cement is best for waterproofing?

Water Repellent Cement is also called Hydrophobic Cement. A small amount of Hydrophobic surfactants such as stearic acid, boric acid or oleic acid is mixed with the ordinary portland cement during grinding of clinker. Hydrophobic Cement is most suitable for basements and for making water tight concrete.

Does PPC cement have grade?

33 Grade, 43 Grade, and 53 Grade OPC cement are available. No specified grade of PPC cement is available.

Can we use PPC instead of OPC?

OPC (m53) attains strength in a shorter time, while PPC (m43) takes longer. PPC on the other hand can attain strength equal to OPC, but takes a longer time. For a building slab, PPC is more widely used since it requires less care.

Which cement is best for construction OPC or PPC?

Recommended use for PPC: In these works, strength is not the major criteria. 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).

Can we use PPC Cement for columns?

Is ppc cement used for columns? - Quora. It could be used, but it'd be a bit tricky as height of the building and exposure to natural forces come into play here. The reason is PPC doesn't resist weathering action well.

What is PPC cement grade?

• OPC cement is available in three grades, such as 33 Grade, 43 Grade, 53 Grade. Portland Pozzolana Cement (PPC): Portland Pozzolana cement is made by grinding pozzolanic clinker with Portland cement. It contains a mixture of OPC, gypsum, and pozzolanic materials like fly ash, volcanic tuffs, rice husk ash etc.

Where is OPC and PPC cement used?

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. The quantity of PPC required in making the concrete is less when compared to OPC.

How many types of UltraTech Cement are there?

UltraTech Cement has 23 integrated plants, 1 clinkerisation unit, 27 grinding units, 7 bulk terminals, 1 white cement plant, 2 WallCare putty plants and more than 100 RMC plants – spanning India, UAE, Bahrain, Bangladesh and Sri Lanka.

Why gypsum is added in cement?

Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the “setting of cement”.
