GB/T 205-2008 in English

《GB/T 205-2008铝酸盐水泥化学分析方法》由TC184（全国水泥标准化技术委员会）归口，主管部门为中国建筑材料联合会。
本标准规定了铝酸盐水泥的化学分析方法。本标准适用于铝酸盐水泥和适合采用本方法的其他铝酸盐类水泥以及指定采用本标准的其他材料。

1 Scope

This standard specifies the methods for chemical analysis of aluminate cement.
Only reference method is specified for the ignition loss determination, insoluble substance determination, total sulfur determination, potassium oxide and sodium oxide determination and fluorion determination of aluminate cement. Reference method and substitution method are specified for the silicon dioxide determination, ferric oxide determination, titanium dioxide determination, aluminum oxide determination, calcium oxide determination and magnesium oxide determination.
This standard is applicable to aluminate cement or other cement of aluminate category suitable for this method as well as other materials designated to be subject to this standard.
