要预防混凝土施工中的碱集料反应导致的工程破坏

PREVENT ENGINEERING FAILURE BY ALKALI AGGREGATE REACTION IN CONCRETE CONSTRUCTION WORKS

本文以广泛的资料介绍了碱集料反应在国内外工程建设中所造成的灾害，分析了其形成原因及机理，系统介绍了这种反应的外观特征、检验方法和预防措施，并针对秦岭隧道和西康铁路其它工程如何预防碱集料反应提出了几点建议。

Based on the widespread informations, the paper introduces the disasters caused by the alkali aggregate reaction occurred in the engineering construction at home and abroad. The cause of its formation and its mechanism are analyzed. The exterior speciality, testing method and preventive measure of this kind of reaction are introduced systematically. In order to prevent the alkali aggregate reaction in construction of Qinling Tunnel and other engineering projects on Xi′an Ankang Railway, several suggestions are proposed also in this paper.
