HAC is a type of calcium aluminate cement, which is manufactured by fusing limestone and bauxite, rather than the limestone and clay/shale used for Portland cement. HAC was used in structural concrete mainly from the 1950s to the early 1970s, most commonly in the manufacture of precast, prestressed concrete beams.

Calcium aluminate cements - Wikipedia

The main active constituent of calcium aluminate cements is monocalcium aluminate (CaAl2O4, CaO · Al2O3, or CA in the cement chemist notation). It usually contains other calcium aluminates as well as a number of less reactive phases deriving from impurities in the raw materials. Rather a wide range of compositions is encountered, depending on the application and the purity of aluminium source used. Constituents of some typical formulations include:
