6、.4TB/'r2922.5-2002前官本标准是根据美国试验与材料学会帆STM)标准ASTMC1260-94《水泥一骨料混合物潜在碱性反应标准试验方法(砂浆棒法)》并结合我国试验室的条件和水平制订的，在主要技术内容上与该标准等同，但在试验程序和方法上作了适当的修改。因此，本标准属于修改采用ASTMC1260-940与本标准有关的系列标准有:TB/1'2922.1铁路混凝土用骨料碱活性试验方法岩相法TB/1'2922.2铁路混凝土用骨料碱活性试验方法化学法TB/T2922.3铁路混凝土用骨料碱活性试验方法砂浆棒法TB/1'2922.4铁路混凝土用骨料碱活性试验方法岩石柱法本系列

7、标准中不同试验方法的具体操作程序各自独立，但试验结果的评定则相互联系，使用者应根据实际情况选取适当的方法进行试验和评定。本标准由铁道部标准计量研究所提出并归口。本标准起草单位:铁道科学研究院铁道建筑研究所。本标准主要起草人:谢永江、汪加蔚、潘庭玉。本标准委托铁道科学研究院铁道建筑研究所负责解释。本标准2002年5月首次发布。中华人民共和国铁道行业标准TB/T2922.5-2002modASTMC1260-94铁路混凝土用骨料碱活性试验方法快速砂浆棒法范围本标准规定了采用快速砂浆棒法检验铁路混凝土用骨料碱
