摘要
参照石灰吸收法,通过测定Ca(OH)2含量,分别研究了在无激发剂、不同浓度NaOH激发剂的情况下增钙煤矸石的火山灰性能。采用X射线衍射和汞压入法等测试方法对各种增钙煤矸石活性评价过程进行了结构层次上的分析。结果表明:各复合体系水化过程的结构特性与体系中Ca(OH)2含量的变化规律基本一致。
Lime absorption, through determining Ca（OH）2 content, pozzolanic performance of added-calciumdoped coal gangue is studied in the condition of no excitant or NaOH of different density. The research of structural level for activity evaluation process of various kinds of added-ealciurrrdoped coal gangue is made by means of X-ray diffraction （XRD） and method of mercury in trusion poreraeasurement （MIP） etc. The experiment can approve that the change on structural characteristic of hydration process of every composite system is consistent basically with that of Ca（OH）2 content.
