摘　　要：废弃玻璃在当今城镇固体废弃物中占有很大比例,大量的堆积引起了一系列的环境和资源浪费问题,而将玻璃用作混凝土原材料可解决废弃玻璃的回收问题。部分发达国家针对玻璃混凝土已开展过大量相关研究,并取得可用于实践的研究成果。随着中国经济的快速发展,开发玻璃混凝土技术是必由之路。通过概括当前废弃玻璃混凝土的主要研究成果,分析废弃玻璃应用于混凝土生产引发的碱-硅反应(ASR)风险,并论述ASR膨胀的影响因素及控制措施。Accounting for a large proportion in municipal solid waste stream,piles of waste glass has contributed to a series of problems such as resources and environmental,and the application of glass in concrete as a kind of raw material can solve its recovery problem.Some developed countries have investigated on glass concrete and had some practical cases,and along with the rapid development of China＇s economy,the development of glass concrete technology is the only way.In this paper,the main research achievements of glass concrete were reviewed,the alkali-silicon reaction（ASR） risk induced by glass was analyzed,and influence factors and control measures of ASR expansion were discussed.
