Bisley also distributes Calumex SC-A, an ultra finely ground, amorphous calcium aluminate. CALUMEX SC-A is the latest development of CALTRA with regard to calcium aluminate technology. It is based on Amorphous Calcium Aluminate—produced by fusing high quality bauxite and lime to form blue coloured round shaped beads. This clinker is than cooled rapidly and ground to a high surface area.

SUPER CEMENT Amorphous (SC-A) from Caltra requires a smaller addition rate to provide RAPID set and RAPID strength development. The ULTRA high Blaine and the Amorphous nature of this material make it highly reactive. It is optimised for use as an additive to Portland cement, to manufacture fast and extremely fast setting cementious mortars.
