国际上因骨料膨胀性反应引起的工程破坏事故,以碱骨料反应的事例占多数,从而引起关注,近十年来就先后召开过五次专题国际学术讨论会加以研讨。本文在龚洛书、朱伯民等人的研究(见本刊1980年6期——以下简称“研究”)基础上,进一步介绍我国南方亚热带湿润气候地区的某工程,使用人造方镁石岩(镁砂)骨料为主要原因的破坏实例。
International accidents caused by the expansion reaction of aggregates have caused a lot of accidents due to alkali-aggregate reactions. This has caused concern. Over the past 10 years, five special international academic seminars have been held to discuss. Based on the research of Gong Luoshu and Zhu Bomin et al. (see the issue of the 6th issue of this publication—hereinafter referred to as “research”), this article further introduces a project in the subtropical humid climate region of southern China and uses artificial magnesite (magnesium). Aggregate is the main cause of destruction.
