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.
