Portland Pozzolana Cement (PPC)
Portland Pozzolana Cement (PPC) is a blended cement that incorporates pozzolanic materials like fly ash to enhance the durability and long-term strength of concrete. This type of cement is especially useful in construction projects exposed to harsh environmental conditions, such as bridges, marine structures, and sewage systems. PPC is known for its ability to gain strength over time, providing enhanced resistance to sulfate and chloride attacks, which makes it a preferred choice for long-lasting infrastructure.
The use of fly ash not only improves the quality of the cement but also contributes to sustainable construction by reducing the carbon footprint. PPC is particularly favored for its workability, as it provides a smoother finish and better cohesion in the concrete mix.
