11 Difference Between Opc & Ppc Cement - Buildpro Store

The most crucial component of a building project is cement, which holds the other components together and assures the structure's strength and durability. The construction's quality is determined by the selection of the proper cement, which comes in two primary varieties.

There has been much discussion about OPC vs. PPC and which one is better suited for a particular construction. 

One can learn more about the difference between OPC and PPC in this post, and which form of cement is best for the construction project.

PPC Cement

  1. Pozzolana is a substance that can be either natural or artificial and contains reactive silica. Cement made from a combination of pozzolanic minerals is known as Portland Pozzolana Cement.
  2. Gypsum, pozzolanic ingredients, and OPC clinker are all included in this cement in varying amounts.
  3. Fly ash, volcanic ash, calcined clay, and silica fumes are some examples of pozzolanic materials.
  4. These ingredients are added in amounts ranging from 15 to 35 % of the weight of the cement.

    OPC Cement

    1. The production of OPC Cement, also known as Ordinary Portland Cement (OPC), involves finely powdering a mixture of limestone and additional raw components such as argillaceous, calcareous, and gypsum.
    2. Three different grades of this cement are offered, including OPC 33, OPC 43, and OPC 53.
    3. The most widely used cement in the world is OPC.
    4. Where construction is done quickly, this sort of cement is favoured. However, the production of OPC has greatly decreased as blended cement like PPC provide benefits including lower energy use and environmental damage.

      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.

      The use of PPC and OPC

      Uses of PPC are listed below:

      1. Given its numerous uses in the building sector, PPC is thought to be a future product.
      2. They are appropriate for usage in challenging environmental circumstances. 
      3. They can be dependably used to build hydraulic structures, maritime constructions, masonry mortars and plastering. 
      4. They are frequently utilised in large-scale concreting projects like dykes, sewage pipes, dams, etc. Every other programme that makes use of OPC also uses PPC.

        Uses of OPC are listed below:

        1. OPC is the most commonly used cement worldwide. 
        2. The cost of production is not expensive making it the sought-after cement in the building industry. 
        3. They are widely used for the construction of high-rise buildings, roads, dams, bridges, and flyovers.
        4. OPC is used for making grouts and mortars. OPC is ideal for the construction of residential and industrial complexes.

          OPC and PPC Grade

          OPC is categorised by the Bureau of Indian Standards (BIS) into three separate grades: 33 grade, 43 grade, and 53 grade. 33 grade is typically not chosen where a high grade of concrete, namely M-20 and higher, is required due to its limited compressive strength. 43 grade is frequently used for a variety of purposes. 

          This grade is particularly well-liked in the building sector. The high strength of 53 grade can meet the requirement for strong concrete. Though the higher grade cement is significantly stronger and more durable, the chemical makeup of OPC 33, OPC 43, and OPC 53 grades is the same. However, according to BIS, PPC currently has compressive strength that is comparable to 33-grade OPC.

          Advantages of OPC (Ordinary Portland Cement)

          1. OPC is suggested for projects where props will be removed early because it sets up faster than PPC.
          2. Greater starting strength than PPC.
          3. Reduced curing expenses as a result of a shorter curing time.

            Advantages of PPC (Portland Pozzolana Cement)

            1. Environmental contamination is decreased through PPC's usage of natural and industrial waste.
            2. PPC is utilised in the construction of dams, foundations, buildings close to the seashore, reservoirs, and marine structures because it is very resistant to sulphate attacks.
            3. PPC costs less than OPC.
            4. PPC begins with a lesser initial strength than OPC, but with proper curing, it gradually becomes harder.
            5. Best option for masonry, plastering, and mass concreting.
            6. High toughness in comparison to OPC.

              Which Cement is Better For The Construction Project?

              Which is better, OPC vs PPC cement is a common question. In conclusion, PPC is typically employed in residential settings, whereas OPC is frequently used in commercial settings.


              I hope a clear chart stating the difference between opc and ppc has clear all your doubts regarding it.


              Cement is used frequently in the building. Today, PPC is replaced in place of OPC. PPC is an adaptation of OPC that increases the strength of the concrete by adding a mixture of pozzolanic material. PPC reduces the amount of OPC used to make concrete as well.

              A green substance that supports sustainable growth. In light of these elements, PPC edges over OPC by a small margin. However, it is challenging to draw a firm judgement.
