Introduction of Cement

Cement is prepared by heating limestone with small quantities of other materials (such as clay shells, silica and sand) to 1450°C in a kiln. The resulting hard substance, called ‘clinker’, is then ground with a small amount of gypsum into a powder to make ‘Cement’, the most commonly used type of cement. This cement is called Ordinary Portland Cement.

Mohta Cement Pvt. Ltd is one of the leading manufacturer and supplier of OPC Cement and PPC Cement.

Introduction of OPC and PPC Cement

(OPC) Ordinary Portland cement-

It is the most common cement used in general concrete construction when there is no exposure to sulphates in the soil or groundwater.OPC is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most non-specialty grout.

(PPC) Portland Pozzolana Cement-

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.

Portland Pozzolana Cement also commonly known as PPC cement. These types of cement are manufactured by using pozzolanic materials as one of the main ingredient. The percentage of pozzolanic material used in the preparation should be between 10 to 30. If the percentage is exceeded, the strength of cement is reduced.

Difference Between OPC and PPC Cement

• Portland Pozzolana Cement is a variation of Ordinary Portland Cement. Pozzolana materials namely fly ash, volcanic ash, are added to the OPC so that it becomes PPC. Pozzolana materials are added to the cement in the ratio of 15% to 35% by weight.
• Both are ecofriendly materials but Pozzolana Cement uses natural and industrial waste thus reducing the environmental pollution.
• OPC is available in 3 grades namely grade 33, grade 43 and grade 53. Pozzolana is available in one grade and its strength matches the strength of grade 33 OPC after curing.
• OPC is the most commonly used cement in construction. PPC is highly resistant to sulphate attacks hence its prime use is in construction of dams ,foundations , buildings near the sea shore , reservoirs , marine construction to name a few.
• PPC is cheaper than OPC.
• PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing.
• OPC Cement is prepared from a mixture of limestone and raw argillaceous & calcareous materials and gypsum like argillaceous, calcareous, gypsum. PPC Cement is prepared by adding Pozzolanic materials to OPC Cement
• OPC generates more heat during hydration reactions making it unsuitable for mass casting. While PPC has a slow hydration process due to which heat generation is comparatively lower.
