The key types of cement are OPC and PPC. OPC stands for Ordinary Portland Cement and PPC stands for Portland Pozzolana Cement. is the most common form of cement.

1. It is manufactured by heating limestone with a number of other elements.
2. Also known as blended cement) is made by blending 15% to 35% of the cement weight with fly ash, volcanic ash etc.
3. To OPC cement.
4. Both OPC and PPC cement can be used in building construction depending on the application.
5. One of the key characteristics of cement is the quantum of compressive strength achieved in 28 days of setting.

cement is expected to achieve 53 MPa of compressive strength in 28 days of setting. Thus, 53 grade cement is stronger than which in turn is stronger than 33 grade cement. The following table captures the differences between the cement types on various key attributes:

Particulars
	53 grade	43 grade
Strength	Highest strength	Lesser strength than 53 grade	Lesser than 43 grade OPC. Strength equivalent to 33 grade OPC
Speed of construction	Gains strength quickly	Takes time for achieving strength	Takes even longer than 43 grade to gain strength
Need for watering	Since it gains strength faster, proper watering is required to avoid cracking	Requires relatively lower maintenance such as regular watering etc.	Requires even lower maintenance than 43 grade OPC
Usage	All high load bearing elements – RCC structures like footing, column, beam and slabs	All masonry work – brick works, plaster, tiling and waterproofing	Same as OPC. PPC has better workability and gives smoother finishes because of its fly ash content
Cement price	This grade carries the highest cement price	43 grade cement price is slightly lower or equal to 53 grade	PPC cement price is generally the lowest amongst all forms

is preferable for load bearing structures like foundation, columns, beams etc. PPC grade cement is more preferable for plastering and finishing work. Buying a new house is just the start of new adventures. One of the most critical step is identifying and procuring the right material and fittings,

What is the disadvantage of OPC cement?

Disadvantages of Ordinary Portland Cement –

1. It cannot be used for mass concreting as it has high heat of hydration as compared to PPC.
2. The durability of concrete made using OPC is less than that of the concrete made using PPC.
3. It produces comparatively less cohesive concrete than PPC, hence concrete pumping becomes a little difficult.
4. OPC has lower fineness, hence has higher permeability and as a result it has lower durability.
5. OPC is costlier than PPC.

Which is more durable OPC or PPC?

Best cement: OPC or PPC? – Both Ordinary Portland and Portland Pozzolana types of cement are widely used for construction purposes. OPC is produced by simply grinding limestone and secondary materials to a powder; and the Portland Pozzolana is a variation of ordinary Portland with an added mixture of Pozzuolanic materials like Fly ash, volcanic ash, clay, slag etc in the ratio of 15% to 35% by weight, which increases the strength of the concrete.

Both OPC and PPC are eco-friendly materials but Pozzolana Cement is made of natural and industrial waste. OPC is available in 3 grades as grades 33, 43 and 53 and Pozzolana is available in only one grade and its strength is equal to the strength of grade 33 of OPC 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. PPC is highly resistant to sulphate attacks and thus it has its applications in mass concrete work like dams, huge foundations, and buildings near seashores, reservoirs and in other marine works.

Which cement is best for bricks?

Use of Cement – OPC – 43 Grade : 43 grade OPC cement is used in masonry as well as wall plastering works, RCC and Non-RCC structures, pathways, etc. OPC – 53 Grade : 53 Grade OPC cement is used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars, etc. You can use different types or grades of cement for different elements of a building.I.e. use 53 grade cement for concreting the structural members like footing, column, etc. and use 43 grade cement for the plastering, infill brick work, flooring work, etc.

• In fact, it is better to use 43 grade cement for plaster work, etc.
• As high strength cement produces shrinkage cracks in plaster.
• It is advisable that, use lower grade cement in the plastering, infill brick masonry work, etc.
• Where strength does not matter.
• Higher grade cement results into high strength but it produces high heat of hydration when mixed with water which may result in cracks on the surface of plaster or concrete as described above.

The manufacturers produce different types of cement to meet different physical and chemical requirements for specific construction projects. Sometimes ordinary Portland cement (OPC) or Portland Pozzolana Cement (PPC) may not be compatible. In such cases, we have given detail information of different types of cement, which a civil engineer must know.

Can we use PPC cement for footing?

What is the difference between OPC & PPC cement,full form of OPC cement is ordinary Portland cement and full form of PPC cement is Portland pozzolana cement. Hi guys in this article we know about cement ppc vs opc and difference between OPC and PPC cement.

Generally ordinary Portland cement is known as OPC and Portland cement mix with pozzolana material about 15-30 ℅ is Portland pozzolana cement that is PPC. 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. PPC cement full form :- PPC cement full form is Portland pozzolana cement. And Let us discused about difference between OPC and PPC cement and cement PPC vs OPC.

What is the advantage of OPC over PPC?

Difference Between OPC and PPC Cement – In the following table is the comparison between OPC vs PPC :

OPC is made by preparing and then grinding a mixture of limestone and additional raw materials including argillaceous, calcareous, and gypsum.	Pozzolanic components are added to OPC to create PPC. OPC clinker, gypsum, and pozzolanic elements (15–35 %), such as calcined clay, volcanic ash, fly ash, or silica fumes, make up the primary constituents.
Compared to PPC, initial strength is higher.	Over a lengthier time frame, PPC has more strength than OPC.
It is less suited for bulk casting because the hydration reaction produces more heat than PPC does.	It produces less heat than OPC because its hydration process is slow.
less resilient in harsh weather.	less costly than OPC.
More costly than PPC.	Cheaper than OPC.
Emits CO2 when it is being manufactured.	It contains both industrial and organic waste, making it environmentally favourable.
It is suitable for quick construction but unsuitable for bulk concreting due to the heat-related difficulties outlined above.	For all kinds of construction activities, it is appropriate. For instance, mass concrete pouring for bridges, RCC casting of structures, and even plastering and other non-structural activities.
Inferior to PPC. It takes 30 minutes to set initially, and 280 minutes to set completely. The quicker setting time facilitates quicker building.	PPC requires more time to set than OPC. It takes 30 minutes to set initially, and 600 minutes to set completely. Better finishing is made possible by the slower setting time.
OPC has 225 sq.m/kg of finiteness. It is less finely ground than PPC. As a result, it is less durable due to its increased permeability.	OPC has a 300 sq.m/kg finiteness. It has a finer texture than OPC. As a result, it is more durable due to its decreased permeability.
OPC cement is available in grades 33, 43, and 53.	No specified grade of PPC cement is available.
Lower than PPC.	Superior to OPC.
It is less resistant to alkalis, sulphates, chlorides, and other substances.	It is more resistant to alkalis, sulphates, chlorides, and other substances.

What is the disadvantage of PPC cement?

Introduction to PPC (Cement): There are more than a dozen types of cement, Each type has its own advantages and disadvantages. PPC is one of them with its own distinctive qualities, that make it popular all around the world. PPC stands for Portland Pozzolana Cement. Uses of PPC: PPC is more durable than Ordinary Cement, because of its resistance against Sulfate, water, and other chemical attacks. Portland Pozzolana Cement is used in the construction of buildings near seashores, dams, marine structures, dams, and other constructions in damp places. Underwater bridge piers and abutments are also constructed by means of this type of cement.

1. For the construction of hydraulic structures.
2. Used in the construction of massive structures like bridge piers, dams, and other thick foundations.
3. It is used in drainage and sewage and sewerage systems.
4. Bridge decks are constructed with RCC made of PPC.
5. Building near seashores is prone to sulfate attack, therefore the use of OPC is not suitable in seashore constructions. PPC is the best option in such circumstances.
6. As at a later stage of hydration, the hardness of PPC is greater than that of OPC, therefore a huge foundation, high walls, dams, and other gigantic structures are made with PPC.
7. Canals and canal falls are constructed by means of PPC, as they are invincible before the attack of water and water-soluble salts.
8. Barrages, which remain merged in the water for a longer period of the year are also constructed with PPC cement.
9. Underground basements are constructed with PPC, as it is resistant to moist surrounding

Chemical Composition of PPC: Portland Pozzolana Cement is made from 45% to 60% OPC and 40% to 55% Pozzolanic Material. Thus the Chemical composition of Portland Pozzolana Cement is:

Compound	Formula	Shorthand form	% by weight
Tricalcium Aluminate	Ca 3 Al 2 O 6	C 3 A	7 %
Tetracalcium Aluminoferrite	Ca 4 Al 2 Fe 2 O 10	C 4 AF	5 %
Belite or Dicalcium Silicate	Ca 2 SiO 5	C 2 S	11 %
Alite or Tricalcium Silicate	Ca 3 SiO 4	C 3 S	25 %
Sodium Oxide	Na 2 O	N	2%
Potassium Oxide	K 2 O	K
Gypsum	CaSO 4,2H 2 O	C S H 2	5 %
Pozzolanic Ash			45%

Advantages of PPC:

1. The soluble calcium hydroxide is converted into insoluble cemented ingredients, thus making the structure impervious/impermeable to water.
2. The production of Calcium Hydroxide is not as much as it is in OPC. The low level of calcium hydroxide significantly provides all-round strength and durability to the concrete structure.
3. The silicate formation in concrete made of PPC continues even after the slowing down of hydration. The process of hardening of Ordinary Cement lasts by the end time of hydration, while the process of hardening of PPC continues even after the completion of the hydration process. The compaction and hardness continue up to 90 days.
4. The modulus of elasticity of PPC is lesser at the earlier stage of cementing, and greater at the later stage than OPC. On the other hand, the modulus of elasticity of OPC at initial age is higher than PPC, and at a later age, it is lesser than PPC.
5. Concrete becomes porous and permeable if it has void spaces. PPC made structures are generally less porous because most of the lime is dissolved during early hydration. Once the structure is set, the soluble silica forms an insoluble cementitious compound, which fills the voids, vacuoles, and hollow capillaries.
6. The generation of heat of hydration is lower than OPC.
7. The setting time of concrete is prolonged, which helps the mason for good finishing of concrete or cement mortar. The cohesiveness of the concrete mix helps for better finishing of concrete.
8. It also prohibits micro-cracks in the structure, which further increases the strength of the concrete structure.
9. If there is enough moisture, the durability and strength further increase after passing a period of 90 days. The long term durability of the PPC is greater than the OPC.
10. The particles of Pozzolanic Cement are spherical, which provides fineness to the surface of the constructed structure.
11. This type of cement bleeds less. Bleeding means some of the water of fresh concrete tends to rise up on the surface of the concrete structure. The high ratio of water at the surface will make the surface too wet, resulting in porous, weak, and nondurable. PPC prevents bleeding.
12. This is economical because about 30 to 45 percent of OPC is replaced by natural products; pozzolana/ volcanic ash.

Disadvantages of PPC:

1. Dismantling of shuttering early is very harmful to the constructed structure because the early hardening of the PPC is lesser than that of OPC.
2. It does not prevent the reinforced steel from corrosion due to the alkalinity reduction.
3. Setting time is longer than that of OPC. The ordinary setting time for OPC structures is 600 minutes or 10 hours.

What is the disadvantage of OPC cement?

Disadvantages of Ordinary Portland Cement –

1. It cannot be used for mass concreting as it has high heat of hydration as compared to PPC.
2. The durability of concrete made using OPC is less than that of the concrete made using PPC.
3. It produces comparatively less cohesive concrete than PPC, hence concrete pumping becomes a little difficult.
4. OPC has lower fineness, hence has higher permeability and as a result it has lower durability.
5. OPC is costlier than PPC.

Why PPC is cheaper than OPC?

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 that of OPC.
