摘　　要：废玻璃最为常见的处理方法是进行填埋处理,这不仅污染环境,也浪费资源。废玻璃因其硬度较高、吸水率较低和易获取等特点得到了研究人员的广泛关注,将废玻璃作为骨料或掺合料应用于混凝土中逐渐成为研究热点。本文首先对废玻璃的种类及物理、化学性质进行了总结,说明了废玻璃作为建筑材料的可行性;在此基础上归纳了国内外学者将废玻璃作为混凝土中的粗骨料、细骨料和掺合料的研究现状;然后论述了影响废玻璃混凝土性能的关键因素,深入探讨了如何激发玻璃粉活性以及如何避免碱硅酸盐反应等问题。最后,指出了废玻璃作为建筑材料存在的问题,以期为今后废玻璃作为建筑材料的资源化利用提供参考。Landfill disposal of waste glass is the most common disposal method,which pollutes the environment and is a waste of resources.Waste glass has received much attention from researchers because of its high hardness,low water absorption,and easy accessibility.The application of waste glass as aggregates or admixtures in concrete has gradually become a hot research topic.This paper firstly summarizes the types,physical properties,and chemical properties of waste glass.Additional,this paper explains the feasibility of waste glass as a construction material.On this basis,it summarizes the research status of domestic and foreign scholars on the use of waste glass as coarse aggregate,fine aggregate,and admixture in concrete.Then,it discusses the key factors affecting the performance of waste glass concrete.After that,it discusses in depth how to stimulate the activity of glass powder and how to avoid alkali-silicate reaction.Finally,the problems of waste glass as construction materials are pointed out to provide a reference for future resource utilization of waste glass as construction materials.
