摘要
本文从碱集料反应条件及碱集料反应对桥涵结构混凝土造成的严重破坏,预防发生碱集料反应破坏应采取的措施,现阶段集料碱活性检测和标准,从而降低在桥涵混凝土施工中碱集料反应发生的机率。
Alkali-aggregate reaction conditions and the alkali aggregate reaction will cause serious damage to the concrete of bridge and culvert structure. In order to reduce the probability of AAR occurrence in construction of concrete of bridge and culvert structure, this paper discusses the measures to prevention of the occurrence of AAR, and test method or standard to detect activity of aggregate alkali.
