Which grade cement is best for PCC?

For PCC concrete works, generally, M15 is used. For reinforced concrete construction minimum M20 grade of concrete is used.

Which cement is best for PCC?

Portland Pozzolana Cement (PPC):

PPC cement is generally used for plastering, brick masonry and waterproofing works. 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.

Which cement is better 43 grade or 53 grade?

OPC 53 grade cement has better quality, strength, and less setting time compared to 33 and 43 grades of cement. Due to its high strength, is used for making concrete of higher grade (Above M20).

Which grade of PPC cement is best?

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. Here, S stands for Sleepers. OPC 33 grade, 43 grade and 53 grade cements are used for General purpose engineering such as building construction.

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.

Concrete vs Cement | The Difference Between Concrete

What is OPC and PPC cement?

PPC (Portland Pozzolana Cement) is a variant of OPC (Ordinary Portland Cement.) These two type of cement differs from each other in terms of component, strength, heat generation, the percentage of several components, durability, grades, cost, eco-friendly nature, application, setting time, curing period etc.

What is OPC 33 grade cement?

OPC 33 Grade:

The 33 Grade portland cement is more workable as compared to other grades of portland cement. It is generally used as a mortar for plaster and masonry works.

Where is PPC and OPC cement used?

Use of PPC and OPC

They can be reliably utilized in the construction of marine structures, masonry mortars and plastering, hydraulic structures. Besides, they are popularly used in mass concreting works, such as dykes, sewage pipes, dams, etc. PPC is also employed in all other applications where OPC is used.

Which 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.

Can PPC be used for RCC?

For the construction of concrete slab both the OPC & PPC cement can be used.

What is PPC cement grade?

PPC Grade Cement (Portland Pozzolana Cement)

PPC grade cement is a type of Portland cement characterized by the presence of pozzolana particles like fly ash, volcanic ash which is added to OPC in the ratio of 15% to 35%. The cement is available in any specific grades. It is finer and less dense than OPC.

Where is 43 and 53 grade cement used?

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.

Can we use 43 grade cement for slab?

Can We Use 43 Grade Cement for Slab? Unless a project requires very high strength cement, the use of 43 Grade OPC is generally recommended in general civil construction work such as residential, commercial and industrial structures. It is used in RCC works, preferably where the grade of concrete is up to M-30.

Which grade of OPC is best?

OPC 53 grade Cement

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. So, We can also mix fly ash (at least 20% by weight of cement) in concrete as part replacement of cement at site.

Where is PPC cement used?

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.

What is OPC cement used for?

Its uses include pavements and sidewalks, reinforced concrete buildings, bridges, railway structures, tanks, reservoirs, culverts, sewers, water pipes and masonry units.

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.

Which cement is cheaper OPC or PPC?

OPC is the most commonly used cement in construction. PPC is highly resistant to sulphate attacks hence its prime use is in construction of dams ,foundations , buildings near the sea shore , reservoirs , marine construction to name a few. PPC is cheaper than OPC.

What is the difference between OPC 43 Grade 53 grade cement?

OPC 43 means that the cement is expected to reach a compressive strength of 43 MPa in a cube cast by 28 days. Similarly, OPC 53 reaches 53 MPa by 28 days. There is a contrasting difference in the setting times of these cements. OPC 53 sets quicker than OPC 43 and has a quite low initial setting time.

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.

Where is OPC 53 used?

OPC 53-Grade- It is mostly used in RCC structures, buildings, pre-stressed concreting, 53 Grade attains 27 Mpa in 7days compared to 23 Mpa by 43-grade cement and achieves a final compression strength of 53 Megapascals in 28 days.

Is 43 grade cement good for house construction?

43 Grade OPC Cement is recommended for plastering ,tiling , masonry works, Non-RCC structures, pathways etc. where initial days strength is not of prime importance.

What does 33 43 and 53 grades of cement mean?

By the grade of cement as 33/43/53, the values 33/43/53 indicate the compressive strength of cement cube in Mpa (N/mm2) after 28 days of curing, where cement mould size is 7.06 cm*7.06 cm*7.06 cm. However, it would be good to understand the logic and basis of arriving at such values.
