High Alumina Cement: Manufacture and Properties | Concrete Technology
During the setting of the high alumina cement (HAC) the important reaction is the formation of mono- calcium aluminate deca-hydrate (CAH 10), dicalcium aluminate octa-hydrate (C 2 AH 8) and alumina gel (AHn).These aluminates develop high strength in the high alumina cement concrete but these aluminates are unstable and convert gradually to tri-calcium alumina hexa-hydrate (C 3 AH 6) and ...
