Calcium Aluminate Cement: Advantages And Disadvantages
Pros: Unsurpassed thermal resistance (up to 1,200 ° C), sulfate deterioration immunity, rapid toughness advancement, reduced permeability, and bio-compatibility for clinical applications. Its extraordinary performance in aquatic environments (e.g., seawater desalination plants) is extraordinary.
Disadvantages: Dramatically greater price (2– 3x Rose City Cement), moderate long-lasting stamina (28-day toughness ~ 45 MPa vs. Portland’s 50+ MPa), and minimal availability in remote areas. The preliminary setup time calls for accurate organizing, requiring proficient labor for optimum results.
Portland Cement: Pros and Cons
Pros: Cost-effective (lowest manufacturing price per bunch), extensively documented performance history, superior long-term compressive stamina (50– 60 MPa), and prevalent international supply chain. Its versatile blendability with admixtures (like silica fume for improved resilience) makes it essential for conventional jobs.
Cons: Prone to sulfate strike in acidic soils, poor performance over 300 ° C( creating spalling), and high water permeability necessitating added waterproofing layers. In essential infrastructure like nuclear centers, its restrictions become inappropriate.
