摘　　要：通过采用GB176-2008《水泥化学分析方法》中的EDTA滴定差减法测定钙镁、氧化钙的含量来推算出氧化镁的实际含量,来分析其返色现象,即溶液先变为红色,随之快速呈现出翠绿色。以此来提高水泥的质量,为提升建筑工程整体质量提供有利的依据,进而推动水泥材料行业的发展。The EDTA titration subtraction method in GB176-2008"Cement Chemical Analysis Methods was used to determine the content of calcium magnesium and calcium oxide to calculate the actual content of magnesium oxide to analyze its color reversion phenomenon,that was,the solution turned red first,and then quickly showed emerald green.In this way,the quality of cement was increased,which provided a favorable basis for improving the overall quality of construction projects,and then promoted the development of the cement material industry.
