Calcium Aluminate Cements (CAC): Chemistry, Properties, Applications, Global Suppliers & Market Outlook: Applied Intelligence
Calcium Aluminate Cements (CAC): What they are, properties, how they’re made, suppliers, trade flows & market potential Calcium Aluminate Cements (CAC): a field guide for engineers & buyers CAC / HAC Refractory Rapid set Sulfate & acid resistance 1) What are calcium aluminate cements? Calcium aluminate cements (CAC, also called high-alumina cements) are specialty hydraulic binders made primarily from limestone (CaO) and bauxite/alumina (Al₂O₃) . They differ from Portland cement: their main clinker phases are aluminates (not silicates), which gives CAC very fast strength gain, high temperature performance and strong chemical resistance. [S1] Chemistry & key phases (cement chemist notation) Phase Formula Notes CA CaO·Al₂O₃ Dominant phase in many CAC grades CA₂ CaO·2Al₂O₃ Higher alumina, slower hydrate kinetics C 12 A 7 (Mayenite) 12CaO·7Al₂O₃ Reactive, contributes to very early set Hydra...
