Introduction of Manufacturing Process of Portland Pozzolana Cement

Portland pozzolana cement is a kind of blended cement, which is produced by either intergrinding of OPC clinker along with gypsum and pozzolanic materials or blending the OPC clinker with powdered pozzolanic materials. In order to improve the cement properties, such as workability, durability and heat of hydration, the concept of using blended cements has been introduced. The main constituents of PPC are clinker, gypsum and pozzolanic materials in the required proportion. The manufacturing process of Portland Pozzolana Cement is simplified. The major raw materials for the manufacture of PPC are clinker, gypsum and fly ash.

The manufacturing process

Manufacturing Process of Portland Pozzolana Cement (PPC)

• The raw materials for Portland pozzolana cement are clay, shale or fly ash, limestone, gypsum, and pozzolan
• Portland pozzolana cement is manufactured by mixing these raw materials together in the proper proportions and grinding them to a fine powder
• The resulting mixture is then burned in a kiln at a temperature of about 1450 degrees Celsius
• This process causes the raw materials to chemically react with each other and form a new compound, known as Portland cement.

Properties of Portland Pozzolana Cement(PPC)

• Portland Pozzolana Cement(PPC) 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 blending of OPC cement with Pozzolanic Portland Cement
• The later process involves adding up to 40% of a pozzolanic material in terms of cementitious value.

  PPC provides extended setting time compared to OPC

• It exhibits enhanced water-resistant and sulfate-resistant properties as well
• The hydration heat evolution of PPC is lower than that of OPC
• It also provides superior workability and finish
• PPC has compressive strengths comparable to those of OPC at all ages.

  PPC is suitable for all types of concrete construction, including massive structures, pre-stressed concrete, underwater concrete, and many others.

Investigation Result on PPC Cement

• It is found that PPC Cement is one of the most commonly used cements in South Africa
• It is also found that PPC Cement is suitable for a variety of applications including concrete, mortar, grout, and plaster
• PPC Cement is also found to be durable and weather resistant.

Advantages of Portland Pozzolana Cement (PPC)

• Portland Pozzolana Cement (PPC) is a type of blended cement which consists of Portland cement and pozzolana materials
• Pozzolana materials are usually volcanic ashes or industrial wastes, such as fly ash or rice husk ash.

  PPC has a number of advantages over other types of cement

• It is more resistant to chemical attack and weathering, making it ideal for use in outdoor applications
• PPC is also more workable than other types of cement, making it easier to use for construction projects.

  PPC is not as widely available as other types of cement, but it can be ordered from specialty suppliers

• It is more expensive than other types of cement, but the increased durability and workability may make it worth the extra cost.

Conclusion

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. This Portland Pozzolana Cement is commonly known as PPC cement. In this manufacturing process, first of all, OPC clinker is produced in the cement factory. Pozzolanic materials available in the vicinity of cement plants are brought to the factory premises. The clinker, gypsum and pozzolanic materials are separately stored in their storage tanks. From the storage tanks, these materials
