Time and experience have shown that the primary causes of these collapses were poor construction details or chemical attack, rather than problems with the concrete itself. Portland cement hardens more quickly, but takes longer to achieve the strength found in hardened calcium aluminate cement. It is manufactured from limestone or chalk and bauxite (Special clay having extremely high alumina content). CSA cements may also be used to manufacture shrinkage compensated or low shrinkage concretes, grouts and mortars. First, the desired crystalline phases of calcium and strontium aluminates, i.e. Calcium aluminate cement (CAC) has been widely applied in many industrial applications owing to its advanced properties, such as suitable rheological properties for workability in refractory castables, outstanding green mechanical strength and resistance to a wide range of chemically aggressive conditions [1–4]. dodeca-calcium hepta-aluminate (Ca 12 Al 14 O 33), C 12 A 7, and tri-strontium aluminate (S 3 Al 2 O 6), S ˇ 3 A, were obtained by Solution Combustion Synthesis and characterized.
