Is There any Difference Between OPC and PPC Cement

Cement is a Construction Material which assumes an imperative part in making cement and mortar. OPC and PPC concrete are most generally utilized. Presently a days PPC is utilized as a substitution to OPC. Along these lines, the most confounding thing is the means by which to settle on the right decision. There is no compelling reason to aimlessly take after the pattern. Knowing their properties, prescribed utilizations, money saving advantages, and so forth will give you a superior thought regarding which concrete ought to be utilized and where it ought to be utilized.


OPC: Ordinary Portland Cement

  1. It is the most surely understood cement used as a piece of the world generally because of the riches and negligible push to convey it.
  2. OPC is made just by pulverizing limestone and discretionary materials to a powder.
  3. Producers now day by day don’t make OPC and have changed to PPC.


PPC: Pozzolanic Portland Cement

  1. Portland Pozzolana Cement (PPC) is a variety of OPC which incorporates a blend of a pozzolanic material which is known to expand the quality of cement and lessen the measure of OPC utilized.
  2. Presently multi-day It is being utilized as a substitution to OPC as it is known to satisfy green building criteria and consequently helps in feasible improvement.

Crude Materials


  1. Calcareous (material containing lime).
  2. Argillaceous (material containing silica and alumina).
  3. Gypsum.

Every one of these materials is blended in a settled extent, are warmed in furnaces and to frame clinkers which are then crushed to expected fineness to acquire this cement.



  1. OPC concrete.
  2. Gypsum.
  3. Pozzolanic material.

Every one of these materials is both combined and granulated or independently crushed and afterward blended to acquire the cement.


Focal Points:


  1. Its setting time is not as much as PPC so it is prescribed in ventures where props are to be expelled early.
  2. It is anything but difficult to deal with when contrasted with PPC.
  3. Its underlying quality is higher than PPC.
  4. Its curing period is not as much as PPC. Henceforth curing cost decreases, subsequently suggested where curing cost are restrictive.


  1. It is the best decision for mass cementing, mortar and stone work.
  2. It can be utilized at any and each place.
  3. It has high sturdiness, implies the structure will last more.
  4. It is impervious to assault against different synthetic substances.
  5. It has higher fineness, consequently has bring down penetrability and accordingly it has high sturdiness.
  6. It is a green material, consequently ecofriendly and accommodating in accomplishing green rating.
  7. It creates more firm solid which can be effortlessly pumped.
  8. It is less expensive when contrasted with OPC.




  1. It can’t be utilized for mass cementing as it has high warmth of hydration when contrasted with PPC.
  2. Higher review like review 53 isn’t prescribed to be utilized for putting as it is known to create shrinkage breaks because of its high quality.
  3. Not very many makers are known to create 33 review of concrete.
  4. It is less strong when contrasted with PPC.
  5. Its protection from forceful synthetic compounds is lower than PPC.
  6. It is known to produce CO2 which is hurtful to nature.
  7. It delivers relatively less strong cement than PPC; subsequently concrete pumping turns into somewhat troublesome.
  8. It is costlier than PPC.


  1. Its setting time is more than OPC.
  2. It is hard to deal with because of its high fineness.
  3. Its Initial quality is lower than OPC. Henceforth props can’t be evacuated early.
  4. Its curing period is somewhat higher than OPC.


Utilizations & Recommendations


  1. Utilization of OPC is exceedingly prescribed where quick pace of development is required.
  2. It can’t be utilized for mass cementing as it has high warmth of hydration.
  3. Higher review like review 53 isn’t prescribed to be utilized for putting as it is known to create shrinkage breaks because of its high quality.
  4. It’s additionally not required to utilize it in brick work as mortar quality in introductory period isn’t that basic.



It can be utilized as a part of all sort of development work Example:


  1. RCC (Reinforced Cement Concrete) work in private and business work.
  2. Mortar and stone work, where high quality isn’t so essential.
  3. Marine Works
  4. In mass solid work e.g. Dams, enormous establishment.
  5. Business and mechanical buildings.
  6. Street, Runway Bridge and flyover,etc.
  7. Additionally suggested for all non-auxiliary cementing like divider mortar.


*Adding different admixtures in solid blend may help in accomplishing speedy setting time. Impediment of higher setting time can be overwhelmed by utilizing legitimate admixtures.




The diverse evaluations of OPC cement accessible in India are:

  • OPC 33 Grade
  • OPC 43 Grade
  • OPC 53 Grade

*Note that a definitive quality relies upon the Mix Design and not on the concrete quality alone.


No particular evaluations of this cement are accessible like OPC.

It is ordered into various kinds relying upon the sort of Pozzolanic material utilized; The diverse pozzolanic materials utilized are:

  • Fly fiery remains
  • Rice Husk fiery remains
  • Volcanic tuffs and Pumicites
  • Clay and Shale

*Fly fiery remains is the most usually utilized Pozzolanic material.
