Portland pozzolana cement (PPC) is a type of cement that is made by mixing pozzolanic materials, such as fly ash or volcanic ash, with Portland cement clinker. PPC cement is known for its strength, durability, and resistance to chemical attacks.
The main difference between PPC cement and ordinary Portland cement (OPC) is the addition of pozzolanic materials in the manufacturing process. PPC cement is generally considered to be more environmentally friendly than OPC cement, as it requires less energy to produce and generates fewer greenhouse gas emissions. PPC cement also tends to have a slower rate of heat evolution and a lower rate of shrinkage compared to OPC cement.
Portland slag cement (PSC) is another type of cement that is made by mixing Portland cement with granulated slag. PSC cement is known for its strength and durability, as well as its resistance to chemical attack and corrosion. Like PPC cement, PSC cement is generally considered to be more environmentally friendly than OPC cement, as it requires less energy to produce and generates fewer greenhouse gas emissions.
In Nepal, some popular brands of PPC cement include Rajdhani Cement, CG PPC, Jagdamba PPC, Arghakhachi Cement, Hongshi Shivam Cement, and Huaxin PCC. It’s always a good idea to do some research and compare prices and quality before choosing a brand of PPC cement for your construction project.
There are several advantages to using Portland pozzolana cement (PPC) in construction projects:
- Strength and durability: PPC cement is known for its strength and durability, making it suitable for use in a variety of construction projects, including foundations, walls, and floors.
- Chemical resistance: PPC cement has good resistance to chemical attacks, making it suitable for use in environments where it may be exposed to chemicals, such as sewage treatment plants and chemical storage facilities.
- Environmentally friendly: PPC cement requires less energy to produce and generates fewer greenhouse gas emissions compared to ordinary Portland cement (OPC), making it a more environmentally friendly choice.
- The slower rate of heat evolution: PPC cement has a slower rate of heat evolution compared to OPC cement, which can be beneficial in mass concrete construction where rapid heat evolution can cause cracking.
- Lower rate of shrinkage: PPC cement has a lower rate of shrinkage compared to OPC cement, which can be beneficial in applications where shrinkage is a concern, such as in the construction of bridges and other large structures.
It’s important to note that PPC cement may not be the best choice for every project. Other factors, such as the specific requirements of the project and local building codes, should also be taken into consideration when choosing cement for building construction.
