What is the advantage of PPC over OPC?

What is the advantage of PPC over OPC?

It generates less heat of hydration at a low rate than ordinary Portland cement. Reduction in permeability of PPC offers many other advantages, such as better durability than opc 53 cement.

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.

Which grade cement is used for RCC?

53 Grade OPC cement is Used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars etc. where initial higher strength is the criteria. 43 Grade OPC Cement is commonly used for plastering works, Non-RCC structures, pathways etc where initial setting time is not of importance.

Which cement is best for roof?

Used in hydraulic structures, marine structures, construction near the sea shore, dam construction etc. Used in pre-stressed and post-tensioned concrete members. As it gives better surface finish, it is used in decorative and art structures.

Does PPC cement have grade?

PPC does not have any grade, only OPC have a grade.

Which cement is good for foundation?

The foundation carries the load of the construction and hence needs to be strong and durable. Portland Pozzolana Cement (PPC) is the ideal cement to be used as it hydrates slowly and gives high final strength. Why Birla.A1 Premium Cement is considered as the best for foundation?

Which cement is used for construction?

1. Ordinary Portland Cement (OPC) Ordinary Portland cement is the most widely used type of cement which is suitable for all general concrete construction. It is most widely produced and used type of cement around the world with annual global production of around 3.8 million cubic meters per year.

Which cement is good for plastering?

However, OPC 53 grade is more preferred due to its comprehensive strength and its long-lasting lifetime. PSC grade cement is used for plastering work primarily in the coastal areas because it provides excellent protection against salt water.

Which is costlier OPC or PPC?

It is less costly as compared to OPC because costlier cement clinkers are replaced by cheaper pozzolana material. 1 bag of PPC (50 kg) gives more volume of mortar than OPC bag as the pozzolanic material is finer and it has lower density.

Which is the best quality cement in India?

PPC has higher strength than OPC over a longer period of time. Generates more heat than PPC in hydration reaction which makes it less suitable for mass casting. It has a slow hydration process and thus generates less heat than OPC. It constitutes industrial and natural waste which makes it eco-friendly.

What is OPC and PPC cement?

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

Is Bharathi Cement good?

Yes! Bharati Cement is a very good brand! I will tell you why… … From, cement products like OPC, PPC, PSC to derivatives and by-products like Aggregates and Laminated PP bags, Bharathi Cements has a good stance in the production of all these products.

Which cement is used for concrete?

ACC Cement is the most commonly used cement in all constructions including plain and reinforced cement concrete, brick and stone masonry, floors and plastering. It is also used in the finishing of all types of buildings, bridges, culverts, roads, water retaining structures, etc.

How many types of cement are there?

There are six different types of cement with specific defining behaviours and chemical compositions. Below we look at each type and what makes them unique. Type I; Ordinary Portland Cement (OPC). This is a general purpose cement with no special properties.

How is PPC cement made?

Portland-pozzolana cement is produced by grinding together Portland cement clinker and artificial pozzolana (Fly ash) with addition of gypsum or calcium sulphate. … Generally 15-25% fly ash is mixed and ground together with 65-75% Portland clinker and 3-6% gypsum to make the best PPC cement in Nepal.

What is the minimum thickness of a slab?

UBC recommends minimum thickness of Concrete floor slabs supported directly on the ground to be 89mm, whereas BCGBC4010A – Apply structural principles to residential low-rise constructions determined minimum thickness to be 100mm.

What is Type 3 cement used for?

Type 1 is a general use cement. Type 2 – Is used for structures in water or soil containing moderate amounts of sulfate, or when heat build-up is a concern. Type 3 – High early strength. … Type 5 – Sulfate resistant portland cement.

What is the strength of PPC cement?

It protects concrete against alkali-aggregate reaction. The minimum compressive strength of PPC after 28 days, as prescribed by BIS is 33 MPa or 330 kg / Cm2. However, the ultimate, long-term strength of PPC is better compared to OPC 53.

How do you test the quality of cement?

The grade indicates the compression strength (N/mm2) of a concrete that will attain after 28 days of setting. 53 Grade Cement means – compression strength of the cement concrete after 28 days of setting, it gives a strength of 53 mpa.(or 53 N/mm2)

What is initial setting time of cement?

The time at which cement starts hardens and completely loses its plasticity is called Initial setting time of cement. The time available for mixing the cement and placing it in position is an Initial setting time of cement.
