世界各国碱集料反应概况

自从1940年美国首先发现碱集料反应引起混凝土工程破坏的事例以来,相继在加、英、日、德、法和南非、丹麦、印度、阿根廷、巴西、瑞士、挪威、荷兰、比利时等国均发现了碱集科反应引起大型混凝土工程破坏的典型事例。近年来我国也已证实碱集科反应造成铁路桥梁、立交桥、机场跑道、轨枕、电线杆及工业民用建筑的破坏。“他山之石,可以攻玉”。回顾各国的概况,吸取他们的经验教训,必将对我国蓬勃发展的大型工程提供有益的启示。

An Overview to Alkali Aggregate Reaction (A. A. K)in The World

Since the concrete engineering damaged by AAR was firstly discovered in AInrica in 1940, the tyPical examples of large scale concrete engineering damaged by AAR were also discovered one after another in Britain, Japan,Germany etc. Recently it was also proved in China that the railway bridge, overpass, airfield runway, sleper, wire pole and industrial - civil enginetring etc. damaged by AAR. Other peple's experienc is of help. Review the geneal situation of other countries and absorp their experience and lesson, it will gain enlightenment for the flourishing large scale project in China.
