摘要
介绍了中国建筑材料联合会标准CBMF 19—2017《混凝土用氧化镁膨胀剂》的技术指标,并与现行国内相关标准进行了对比。结合标准实施两年多来的应用情况,对影响氧化镁膨胀剂使用的几个问题进行了分析,为该标准的后续修订和应用提供参考。
The standard of CBMF 19-2017 Magnesia Expansion Agent for Concrete is introduced.Comparing with similar current standards and specification,the technical indexes in the association standard are discussed.According the feedback suggestions in past two years since the standard implementation,several questions of concern to the industry are analyzed and answered,which can provide some technical references for subsequent revisions and application of the standard.
