我国混凝土中的碱集料反应
Alkaliaggregate Reaction of Concrete in China
【摘要】 介绍了我国已发现的混凝土中活性集料分布及碱集料反应(Alkaliaggregatereaction—AAR)的破坏事例.这包括碱硅酸反应(Alkalisilicareaction—ASR)和碱碳酸盐反应(Alkalicarbonatereaction—ACR).叙述了大型混凝土工程,如立交桥、机场和预应力混凝土铁路桥梁受AAR破坏的典型事例,并叙述了确证AAR的综合判定方法.
【Abstract】 The distribution of reactive aggregates and the destroyed cases caused by alkaliaggregate reaction are described. The typically destroyed cases were flyover bridges, runways of airports, prestressed concrete bridges and sleepers used in railway, which included both alkalisilica reaction and alkalicarbonate reaction. It is emphasized that the confirmation of alkaliaggregate reaction should be comprehensively analyzed.
