Brief: Discover the unbeatable durability of Alumina Cement, a high-performance hydraulic cementitious material perfect for upgrade construction projects. Made from alumina and lime, it offers fast hardening, early strength, and superior resistance to sulfate corrosion and heat. Ideal for emergency repairs, winter construction, and harsh chemical environments.
Related Product Features:
Fast hardening and early strength: Reaches standard strength in 3 days, perfect for emergency repairs.
High hydration heat: Releases heat early, suitable for winter construction but not for large volume projects.
Resistant to sulfate corrosion: Dense structure and low calcium oxide content make it ideal for harsh chemical environments.
Excellent heat resistance: Maintains stable strength at high temperatures, perfect for refractory concrete.
Available in CA-50, CA-70, and CA-80 types, each with unique properties for different applications.
High aluminum content in CA-80 improves setting speed and medium temperature strength of refractory castables.
Not suitable for mixing with Portland cement or lime to avoid instant setting and strength issues.
Packaged in moisture-proof paper bags, ensuring long-term storage and quality.
FAQs:
What are the main types of high alumina cement?
High alumina cement is classified into CA-50, CA-70, and CA-80 types based on aluminum and calcium content, each suited for different applications.
Why is high alumina cement not suitable for large volume projects?
Due to its high hydration heat released early, it can cause temperature difference stress in concrete, making it unsuitable for large volume projects.
Can high alumina cement be mixed with Portland cement?
No, mixing high alumina cement with Portland cement or lime can cause instant setting, preventing construction and affecting strength.
