碱-骨料反应对混凝土的危害及防护措施

Damages and preventions of alkali-aggregate reaction to concrete

碱-骨料反应是全球性的混凝土病害,对结构开裂具有重要影响。文章介绍了这种反应的成因及危害,并提出了在新结构中预防碱-骨料反应的响应措施。

Alkali-aggregate reaction is a common cause of concrete cracking that results in significant damage to concrete structures worldwide.This paper explains the mechanisms of alkali-aggregate reaction,its effects on concrete and methods for preventing deterioration from this cause in new constructions.
