first a bit of background....
A pozzolanic material is a material that will set hydraulically (with the addition of water) when calcium hydroxide is present.
The good thing about this, is that when Cement hydrates and hardens it produces a few chemicals Calcium Silicate hydrate (CSH) which is what gives cement most of it's strength, and Calcium Hydroxide.
This calcium hydroxide is exactly what we need to set a pozzolanic material and hence we can mix them in certain quantities to reduce the need of cement, use waste materials, and improve the qualities of the cement to some degree.
Now back to the question.....
A protland pozzolano cement (PPC) is a cement with an addition of one of this pozzolanic materials. i.e. pulverised fly ash (PFA), ground granulated blast furnace slag (GGBS), silica fume,
A Portland slag cement is a mix between Portland cement and and a pozzolanic material derived from blastfurnace slag.

∙ 9y agoOrdinary Portland Cement (OPC) [or other cementitious materials] has a property of hydraulic setting, binding and hardening when mixed with water.
Some materials undergo hydraulic setting when combined with water in presence of cements, but not by itself. These are called Pozzolanic materials.
In other words, pozzolanic material + water does not set.
Pozzolanic material+water+cement sets.
Examples of pozzolanic materials are fly ash, blast furnace slag, brick powder (surkhi), rice husk ash etc.
A commercial cement formed by mixing proportions of OPC and any pozzolaanic material, is called Pozzolanic Portland Cement PPC. PPC can be made as good, durable and strong as OPC with prooper mixing ratio. It is generally slow setting and sulphate resistant. Moreover, it is environment friendly serving to recycle waste products such as fly ash and slag.
- OPC - Ordianry Portland Cement
- OPC is obtained by adding raw materials like calcareous materials and argillaceous materials.
- PPC - Portland Pozzolona Cement
- PPC is obtained by adding pozzolonic materials like flyash, pumicites, volcanic ashes, shales, tuffs, etc.,

Difference between opc and ppc?
Ordinary Portland Cement, also known as OPC, is a type I cement that does not only harden, but also becomes water-resistant once it cures. Pozzolanic Portland Cement, or PPC, is a type IV cement that includes a mixture of a pozzuolanic material, which can increase the strength of the concrete and reduce the amount of OPC used.
What is pozzolanic cement?
Pozzolanic cement is a cement which consists of pozzolanic materials like fly ash, volcanic ash, pumicite,etc.,A Pozzolan is any material which in the presence of lime and water will react hydraulically to form a cemented massContains pozzolanic materials of 10-95% by weight.Pozzolanic cement can be made from 95 % recycled materialsprovides many improved performance ove OPC. (ordinary portland cement)It is generally used now a daysLess heat evolved when compared to OPC.
What is the difference between src and opc cement?

What is the meaning of ppc cement?
Portland Pozzolana cement (PPC) is manufactured by a combination of pozzolanic materials. Pozzolana is an artificial or natural material that has silica in it in a reactive form. Along with pozzolanic materials in specific proportions, PPC also contains OPC clinker and gypsum. These pozzolanic materials include volcanic ash, calcined clay or silica fumes, and fly ash which makes around 15% to 35% of cement weight.

What is difference between 43 and 53 grade opc cement?
43 grade OPC Cement it denotes the compressive strength of concrete in 43 Mega pascals will attain in 28 days. it is normally used for pavements, Non RCC structures and which are not important for initial strength. where as 53 Grade OPC Cement it denotes the compressive strength of 53 Mega Pascals will attain in concrete with the 28days, and it is used for RCC strengths and which are important to gain initial strength.

What difference between psc cement opc cement?
Psc is always first choice because psc cement gives more strength than opc and also psc cement setting time is slower not that much it will give same strength in 28 days... Because of slower setting cracks will not appear or there is very less chance to appear cracks and it will requires lesser curing than opc..
What is de difference between ordinary portland cement and masonry cement?
Masonry cement is similar to OPC but has a plasticiser added to the cement powder. As a bag of masonry cement contains 75% cement powder and 25% plasticiser, a higher proportion of cement must be used.
What is difference between 43 and 53 grade opc cement?
43 grade OPC Cement it denotes the compressive strength of concrete in 43 Mega pascals will attain in 28 days. it is normally used for pavements, Non RCC structures and which are not important for initial strength. where as 53 Grade OPC Cement it denotes the compressive strength of 53 Mega Pascals will attain in concrete with the 28days, and it is used for RCC strengths and which are important to gain initial strength.
What is Opc and ppc grade of cement?
OPC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and high reactive silica. High reactive silica improves the quality of cement by reducing liberated lime.
What is the difference between portland cement and pozzolan cement?
There are three kinds of cement PPC, OPC. SRC. Portland Pozzolana Cement (PPC) The Portland Pozzolana Cement is a kind of Blended Cement which is produced by either intergrinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions or grinding the OPC clinker, gypsum and Pozzolanic materials separately and thoroughly blending them in certain proportions. Pozzolana is a natural or artificial material containing silica in a reactive form. It may be further discussed as siliceous or siliceous and aluminous material which in itself possesses little, or no cementitious properties but will in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperature to form compounds possessing cementitious properties. It is essential that pozzolana be in a finely divided state as it is only then that silica can combine with calcium hydroxide (liberated by the hydrating Portland Cement) in the presence of water to form stable calcium silicates which have cementitious properties. The pozzolanic materials commonly used are: Volcanic ash Calcined clay Fly ash lica fumes OPC is environment friendly as well as economical Ordinary Portland Cement (OPC-53, OPC-43, OPC-33) OPC-43 GRADE The 43 grade OPC is the most popular general-purpose cement in the country today. The production of 43 grade OPC is nearly 50% of the total production of cement in the country. The 43 grade OPC can be used for following applications: General Civil Engineering construction work RCC works(preferably where grade of concrete is up to M-30) Pre-cast items such as blocks, tiles, pipes etc Asbestos products such as sheets and pipes Non-structural works such as plastering, flooring etc. The compressive strength of cement when tested as per IS code shall be minimum 43 MPa. The physical and chemical properties of this cement are given in the table: Physical Characteristics of 43 Grade OPC (BIS Requirement) Is Code Finene SS (sq.m/k g Min) Soundness by Setting Time Compressive Strength Lechatlier (mm)max Auto clave Max (%) Initial (mts) min Final (mts) Max 1 day Min Mpa 3 day Min Mpa 7 day Min Mpa 28 day Min Mpa (IS 8112- 1989) 225 10 0.8 30 600 Not specified 23 33 43 Chemical Characteristics of 43 Grade OPC (BIS Requirement) Is Code Lime Saturation Factor Alumina Ration Min Insoluble MgO (%) Sulphuric Anhydride Loss ignition (%) Max (IS 8112 - 1989) 0.66 Min 1.02 Max 0.66 3 6 2.5% Max when C3A is 5 or less. 3% Max when C3A is greater than 5 5 Sulphate Resisting Portland Cement (SRC) Sulphate Resisting Portland Cement is a type of Portland Cement in which the amount of tricalcium aluminate (C3A) is restricted to lower than 5 % and (2 C3A + C4AF) lower than 25%. The SRC can be used for structural concrete wherever OPC or PPC or Slag Cement is usable under normal conditions.
What is the classification of cement?
There are 3 types of cement,OPC (Ordinary Portland cement)PPC (Portland pozzolona cement)Special Cements.
Difference between ordinary Portland cement and puzzalona Portland cement?
OPC - Ordinary Portland cementOPC - Materials used - Argillaceous and calcareous materialsPPC - Portland Pozzolona CementPPC - OPC + Pozzolonoc materials(fly ash, volcanic ash, pumicite at the time of grinding).
What is the difference between opc da and opc hda?
OPC DA will access the real time value from control system. OPC HDA will access the real time value of historian processed. Hence the historian will save the value in their database as well as it feed to OPC server also.
