废弃玻璃利用现状及其在混凝土材料领域的应用

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。目前废弃玻璃的回收利用可以分为自身的循环利用与其他领域的应用两大类,而将其应用到混凝土领域里无疑是大量处理废弃玻璃的最佳途径。废弃玻璃既可用作混凝土骨料,又可用做混凝土的掺合料。发达国家对此已开展了多年研究,在各种类型的混凝土中都做了有益的尝试,取得了一些成果。研究表明:将废弃玻璃应用于混凝土中在生态、经济及工程方面都能取得较好的效益,前景十分广阔。

Review on the utilization of waste glass and its application in concrete materials

Accounting for a large proportion in municipal solid waste stream,piles of waste glass has contributed to a series of resources and environmental problems.There are two major ways of recovering and recycling waste glass in now days.One way is recycling in its own industry,another is reusing in other areas.Undoubtedly,the reuse of waste glass in concrete areas is among the most attractive options.Waste glass can be used as either aggregate replacement or admixture in concrete,as is shown in many studies conducted by the developed countries for several decades.Many attempts have been made to produce new kinds of concrete materials with waste glass.Some achievements have been obtained while some problems are still to be solved.The results show that recycling of waste glass in concrete is well promising considering the fact that significant environmental,economical and technical benefits can be achieved.
