    Active Standard: C25 - 19

    Developed by Subcommittee: C07.05 | Committee C07 | Contact Staff Manager



    WK68965


    Keywords

    alternative method; aluminum; available lime index; calcium; carbon; carbon dioxide; chemical analysis; free moisture, lime; free moisture, limestone; free silica; hydrated lime; instrumental analysis; iron; limestone; loss on ignition, (LOI); magnesium; manganese; methods, classical; methods, historical; oxides; oxides, unhydrated; phosphorus; quicklime; reference method; silicon dioxide; Standard Reference Material (SRM); strontium; sulfur;;

    Rationale

    Due to potential color interferences with iron and steel slag due to the presence of iron, utilization of the existing procedure outlined in C25, Section 33.6 is not appropriate for determining the Calcium Carbonate Equivalent of Iron and Steel slags.
