Calcium aluminates are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The product obtained after cooling is a hard mineral: calcium aluminate clinker. Ground into a fine powder, the clinker becomes a calcium aluminate binder which forms a paste when mixed with water. This has the ability to harden and form a rigid solid within less than 24 hours. There are two distinct ways to use calcium aluminates: as high-performance binders and as mineral reactants in a variety of industries.
CALCOAT® RG, Ternal® XF and Ternal® LC are hydraulic binders with an alumina content of approximately 50%. These products are mainly resulting from limestone and bauxite transformation in aluminous clinker furnaces. Ternal® XF and Ternal® LC are specifically designed for flooring applications.
