Abstract

A study on the application of recycled concrete for structural concrete was carried out under the concept of life cycle assessment (LCA) for environmental management of construction utilizing recycled products. Such products are often discarded, when existing electric power plants are rebuilt or upgraded in order to meet increasing power demands. In pursuing the reuse of these recycled materials, the basic policy was composed of three items: (1) the assurance of quality; (2) the reduction of environmental impact; and (3) construction cost. The study is divided into two main parts: feasibility study on the reuse of recycled concrete, and experimental study on the quality of recycled aggregate and recycled aggregate concrete. This paper presents the result of the experimental study on the quality of recycled aggregate and recycled aggregate concrete. Based on the investigation and the analysis of results, valuable data were obtained regarding concept and practice as to the reuse of construction debris based on LCA.

再生混凝土在结构混凝土中的应用——再生骨料和再生骨料混凝土质量的试验研究

在生命周期评价(LCA)理念下，对利用再生产品的建筑环境管理中再生混凝土在结构混凝土中的应用进行了研究。当现有的发电厂为了满足日益增长的电力需求而进行重建或升级时，这些产品往往被丢弃。在追求这些回收材料的再利用方面，基本政策由三项组成:(1)保证质量;(2)减少对环境的影响;(3)建设成本。本研究主要分为再生混凝土再利用可行性研究和再生骨料及再生骨料混凝土质量试验研究两大部分。本文介绍了再生骨料和再生骨料混凝土质量的试验研究结果。通过调查和结果分析，为基于LCA的建筑垃圾再利用的理念和实践提供了有价值的数据。
