Abstract:
A study on 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 quality o Paper aper presents the result of the experimental study on the 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.
