摘　　要：水泥作为一种重要的建筑材料,其质量优劣至关重要。水泥煅烧后,其中的三氧化二铁生成C4AF。当水泥中铁含量过高时,水泥的凝结和硬化过程就会变慢,从而影响水泥的性能。本文依据标准GB/T 176-2017《水泥化学分析方法》,描述水泥中三氧化二铁含量检测方法要点。同时,针对工作中容易出现的问题,总结了检测中应该注意的事项,为使用此方法检测的人员提供借鉴。As one of important building materials,the quality of the cement is crucial.After the calcination of the cement,ferric oxide has reacted and formed into C4AF.And when the iron content is too high in the cement,the setting and hardening processes of the cement will slow down,thereby affecting its performance.This article describes the key points of the testing method for the content of ferric oxide in cement based on the standard GB/T 176-2017 Methods for Chemical Analysis of Cement.At the same time,the article also summarizes the matters that should be noted in the testing process about the problems that are likely to occur during the work,providing references for those who use this method for testing.
