Portland Pozzolana Cement (PPC) is a type of blended cement that combines Portland cement with pozzolanic materials, such as volcanic ash or fly ash. This mixture enhances the cement's durability and resistance to chemical attacks, making it suitable for various construction applications, including buildings, bridges, and roads. PPC is known for its lower heat of hydration compared to ordinary cement, which helps reduce the risk of cracking in large structures. Additionally, its use promotes sustainability by recycling industrial by-products, contributing to eco-friendly construction practices while maintaining strength and performance.
