Hail Portland Pozzolana Cement
Pozzolanic Portland Cement is a type of cement made by blending ordinary Portland cement with pozzolanic materials, which are natural or synthetic substances containing silica and alumina. These materials can react with lime in the presence of water to produce hydroxy compounds. One of the most prominent pozzolanic materials used in this cement is volcanic
ash or pumice.
Pozzolanic Portland Cement is distinguished by several properties, including:
- High permeability: Concrete made from pozzolanic Portland cement is denser.
- Moderate sulfate resistance: It offers good protection against sulfate attack.
- Improved workability: It enhances the ease of mixing and handling during pouring.
- Increased resistance to alkali-aggregate reactions: The pozzolana reacts with alkalis, forming inactive alkali sulfates, which prevent harmful reactions with active aggregates.
Pozzolanic Portland Cement is a value-added product in the construction industry, offering numerous advantages compared to ordinary Portland cement. It is an ideal choice for projects requiring high-strength concrete with resistance to harsh environmental conditions.
