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.

What is the grade of PPC cement?

There are no grades in PPC or in any other type of cement. 43 S grade and 53 S grade of cement are used in Railway Engineering for manufacture of sleepers.

Which is stronger PPC or OPC?

PPC has a lower heat of hydration and it is prone to fewer cracks compared to OPC. PPC has lower strength than OPC but PPC provides better workability and finishing than OPC. PPC provides greater resistance to chemicals.

What is the strength of cement?

For ordinary Portland cement (OPC), compressive strength is ranging between 33 – 53MPa at 28 days, 22- 27 MPa at 7days and 16 -27MPa at 3days of curing after casting. For Portland Pozzolana cement (PPC), compressive strength is 33MPa at 28 days,22MPa at 7days and 16MPa at 3days of curing after casting.

Is PPC cement good for RCC?

Both OPC and PPC cements are good for construction of concrete slab. OPC is the most commonly used cement in industrial and large construction, PPC is most commonly used for small residential constructions. PPC is used where possibilities of sulphate attack is higher as it has good sulphate resistance compared to OPC.

Why Pozzolana portland Cement PPC is more popular | PPC Vs OPC | Benefit of PPC Cement

Where we can use PPC cement?

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.

Is PPC cement good for foundation?

Which type of cement is best for constructing the 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.

What is meant by 53 grade cement?

OPC 53 Grade cement is required to conform to BIS specification IS:12269-1987 with a designed strength for 28 days being a minimum of 53 MPa or 530 kg/sqcm. 53 Grade OPC provides high strength and durability to structures because of its optimum particle size distribution and superior crystallized structure.

What is MPa in cement strength?

Concrete is measured by its strength capacity. MPa (megapascals) is the metric measurement for psi or pounds per square inch. The BC Building Codes require a minimum MPa for specific concrete projects.

What is the strength of concrete after 28 days?

concrete gains 16 percent strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days and 99% strength in 28 days. Thus, it is clear that concrete gains its strength rapidly in the initial days after casting, i.e. 90% in only 14 days.

Can we use PPC cement for footing?

So PPC cement is new variant of OPC cement. Both cements are widely used for the various purpose like beam, slab, concrete manufacturing, brick block, footing and retaining wall formation. And both OPC and PPC cement are eco-friendly in nature.

Which cement is best PSC or PPC?

PSC lessens the risk of shrinkage cracks and cracking. Strength gain is less in PPC and it is also not suitable for high performance concrete and quick concrete setting whereas PSC brings ultimate strength and excellent finish, hence PSC holds the upper hand.

Which cement is best for roof?

The best roof cement in India includes OPC53 grade and PPC cement, brand name Ambuja plus Roof Special Cement, ACC Gold, ACC F2R, Shri Roofon Concrete Master, Ramco Supercrat Cement.

What is the difference between OPC and PPC cement?

Conclusion: Both OPC and PPC are commonly used cements in construction. These days, PPC is used as a substitute of OPC. PPC is a variation of OPC which adds a mixture of a pozzolanic material that helps to enhance the strength of the concrete. PPC also brings down the amount of OPC requirement in making concrete.

Is 32 MPa concrete good?

As a rule of thumb 20mph concrete is fine for foot traffic, I.e., footpaths and house slabs, depending on your sub base, whilst 25 mph is more appropriate for driveways and light traffic. 32mpa and 40mpa concrete is suitable for shed slabs and heavy traffic areas.

What is 25 MPa concrete used for?

Concrete 25 MPa is commonly used in domestic and commercial floor construction and is considered to be a multi-purpose concrete mix. The typical mix ratio is 1:1:2 (cement, sand, coarse aggregate).

What is 40 MPa concrete used for?

Concrete 40 MPa is commonly used in commercial and civil construction, for structural beams and columns, where increased durability and load-bearing capacity are required.

Which is better OPC 43 and OPC 53?

OPC 53 sets quicker than OPC 43 and has a quite low initial setting time. It is used in structures where rapid strength gain is required like large load bearing structures like bridges, huge buildings, etc. OPC 43 on the other hand doesn't set so quickly and has a normal initial and final setting time.

What is OPC 33 grade cement?

OPC 33-grade cement means ordinary portland 33-grade cement. In these, the number 33 represents the compressive strength of cement at end of 28 days of curing and tested as per Indian standard code recommendation.

What is OPC cement?

Ordinary Portland cement (simply called ordinary cement) refers to the hydraulic binding material ground by mixing Portland cement clinker, 6% ~ 15% blended materials, and appropriate amount of gypsum, code-named P• O.

How long does PPC cement take to dry?

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 UltraTech PPC cement?

UltraTech cement is the ultimate 360° building materials destination, providing an array of products ranging from grey cement to white cement, from building products to building solutions and an assortment of ready mix concretes catering to the varied needs and applications.

Which cement is best for house construction?
