IRC50 - alcium Aluminate Cement

IRC-50 is a hydraulic cement with a high alumina content of approximately 50% .  IRC-50 is a fused product with a mineralogy focused on CA to give strong hydraulic activity and impart excellent mechanical properties to conventional concretes.
The low iron oxide content of IRC-50, when combined with appropriate aggregates, makes it particularly suitable for concretes having to withstand carbon monoxide reducing atmospheres.
IRC-50 does not contain any additives, its use is recommended for refractory premixes.
Like other type of hydraulic binders, IRC-50 must be stored in dry conditions. It will retain its properties for at least 6 months, in many instances even its properties are retained for more than one year.
