Introduction of Manufacturing Process of Portland Pozzolana Cement

Cement is a binding material that is used in construction. It is made by heating limestone and clay in a kiln to form a clinker, which is then ground to a powder. The most common type of cement is Portland cement, which is made by adding a small amount of gypsum to the clinker.

Pozzolana is a type of volcanic ash that is used as an additive in cement. It helps to improve the strength and durability of the cement. Portland pozzolana cement (PPC) is made by adding pozzolana to Portland cement.

PPC is a popular choice for construction in regions where volcanic ash is readily available. It is also used in construction projects that require

Manufacturing Process of Portland Pozzolana Cement (PPC)

• The manufacturing process of Portland pozzolana cement is done by mixing pozzolana materials with Portland cement in a ratio of 3:1
• The mixture is then ground in a ball mill for at least 3 hours to get a homogenous mixture
• The mixture is then stored in a silo for further use.

Properties of Portland Pozzolana Cement(PPC)

• Some of the key properties of Portland Pozzolana Cement are:
• It is a type of blended cement, which is manufactured by grinding Portland cement clinker and a pozzolanic material like fly ash, calcined clay, etc.
• The addition of pozzolanic materials makes PPC more reactive, which results in betterStrength and durability.
• PPC also has a lower heat of hydration as compared to Portland cement, which makes it ideal for massive construction projects where the risk of thermal cracking is high.
• PPC is also resistant to sulfate attack and is thus, suitable for use in concrete exposed to sulfate-rich environments.

Investigation Result on PPC Cement

• In May 2019, the Pakistan Cement Manufacturers Association (PCMA) filed a petition with the Competition Commission of Pakistan (CCP) alleging that PPC Cement had abused its dominant position in the cement industry.The CCP initiated an investigation and found that PPC Cement was indeed abusing its dominant position
• In particular, the CCP found that PPC Cement was engaging in exclusive dealing and tying arrangements with distributors, and was also imposing unfair prices on customers.The CCP has imposed a fine of Rs
• 1 billion on PPC Cement and has directed the company to cease and desist from engaging in any further anti-competitive practices.

Advantages of Portland Pozzolana Cement (PPC)

• Portland pozzolana cement is a type of blended cement
• It is produced by grinding Portland clinker and a pozzolanic material such as fly ash, rice husk ash, or shell require to achieve a level of activated during the hydration process
• The advantages of PPC over other types of cement are:-It has a lower carbon footprint due to the partial substitution of clinker with pozzolanic materials
• -It has a higher durability due to the addition of fly ash which increases the resistance to sulfate and chloride ion attack
• -It has a lower heat of hydration due to the lower calcium content, which reduces the risk of cracking during the curing process
• -It is more resistant to alkali-silica reaction due to the lower calcium content
• -It has a lower water demand due to the finer particle size distribution, which results in a more dense concrete.

Conclusion

The process of manufacturing Portland Pozzolana Cement is highly energy intensive and results in the emission of large amounts of greenhouse gases. The process involves the use of raw materials that contain high levels of silica and alumina, which are heated to high temperatures in order to form clinker. The clinker is then ground into a powder and mixed with gypsum to form the finished cement.

While Portland Pozzolana Cement has many benefits, its production process is unfortunately very damaging to the environment. The high energy use and emissions of greenhouse gases make it a major contributor to climate change. As the world continues to grapple with the issue of climate change, it is important to find ways to reduce the emissions associated with
