废弃玻璃建材化研究现状、存在问题及其发展趋势

A Study on the Waste Glass Recycled as Building Materials

随着工业化和城市化进程的加速及城市居民消费水平的提高,生活垃圾数量越来越多,对城市环境产生了很大的影响。废弃玻璃在城市生活垃圾中占有很大比例,因此必须加强对废弃玻璃循环再生利用,特别是废弃玻璃建材化运用的研究,真正实现废弃玻璃处理无害化和资源化的目标。为此,对于废弃玻璃作为混凝土中骨料和掺合料、废弃玻璃在预制混凝土和彩色玻璃混凝土中的应用现状进行归纳总结,分析了废弃玻璃建材化运用过程中的研究现状,提出了废弃玻璃建材化研究中的存在问题和发展趋势。

With the acceleration of industrialization,urbanization and the improvement of consumption of urban residents,the civic environment is greatly influenced by the rapid growth of municipal waste,in which waste glass accounts for a large proportion.The research on recycling waste glass,especially its reuse as building materials should be strengthened to achieve the purpose of decontamination and resource recovery in waste disposal.The paper presents a review on research status of waste glass reused as coarse-fine aggregate,and admixture in concrete,and waste glass reused in precast concrete and color glass concrete.It also analyzes the current problems and development tendency of waste glass reuse as building materials.
