Product Description
Amorphous Calcium Aluminate is a non-crystalline calcium aluminate material characterized by its excellent reactivity, high early-strength performance, and superior chemical stability.
Compared with crystalline calcium aluminate phases, the amorphous structure enables faster dissolution and rapid hydration, making it ideal for high-performance industrial applications. The material exhibits outstanding compatibility with refractory aggregates and demonstrates enhanced mechanical strength development, making it the preferred choice for demanding applications.
Main Applications
- Refractory materials
- Special cement & high-performance binders
- Ceramic formulations
