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.

Does PPC cement have grade?

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.

Which is better OPC or 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. PPC provides greater resistance to chemicals.

Which cement is best 53 grade or 43 grade?

Is PPC cement good?

PPC produces highly durable concrete as it has low water permeability compared to OPC. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing. And PPC is cheaper also compared to OPC.

OPC VS PPC Cement | Difference in Hindi | Which Cement is Best and Why ??

Can PPC be used for RCC?

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

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.

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.

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.

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.

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.

Which cement is best PSC or PPC?

PSC cement is the better then the PPC. The ultimate strength of PSC is high. Chloride & sulfate attack is very dangerous for any type of structure, PSC is only cement who react better opposite to the Chloride and Sulfate. PPC is not suitable for coastal and sea shore area.

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.

Why is PPC cement better than OPC?

The strength of PPC is good than OPC in long terms. It has high heat of hydration making it unfavorable for mass concreting. The hydration process is slower than OPC resulting low heat of hydration. Therefore, it is suitable for mass concreting.

What is m30 cement?

∴ In the designation of a concrete mix, the letter 'M' and the number stands for Mix and characteristic compressive strength of 150 mm cube at 28 days. ∴ The M 30 grade of concrete means the concrete mix which attains 28 day strength (characteristics) as 30 MPa or 30 N/mm².

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 M20 grade concrete?

For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.

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.

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.

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.

What is 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.

Where is used in PPC cement?

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 is difference between PSC and PPC cement?

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.
