摘要
着重介绍了近年来碱集料反应(alkali aggregatereaction,AAR)研究的一些最新成就,包括集料中碱的析出、碱集料反应的分类、集料活性的鉴定方法、湿度的影响及碱碳酸盐反应(alkali carbonatereaction,ACR).由于在世界各地发生AAR的事例增多,对工程的耐久性影响巨大,因而近年来又重新引起重视,甚至在研究最多、最早的美国,现在也已重新开始了研究.此处所述内容希望对重大工程的决策能有参考价值.
This paper reviews the recent progress of studies on alkali aggregate reaction(AAR), which include the release of alkali from aggregate, classification of AAR, method for identification of reactivity of aggregate, the influence of dampness on AAR and alkali carbonate reaction(ACR). Due to the increasing of cases of deterioration caused by AAR which seriously affect of the durability of concrete structure, attention arouses widely again even in USA which found the first case of AAR and studied more carefully than other countries. The description of this paper might have reference role for practice.
