APPLICATION OF RECYCLED AGGREGATE CONCRETE FOR STRUCTURAL CONCRETE. PART 1 – EXPERIMENTAL STUDY ON THE QUALITY OF RECYCLED AGGREGATE AND RECYCLED AGGREGATE CONCRETE

A study on the application of recycled aggregate 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 stations are rebuilt or upgraded in order to meet increasing power demands.

In pursuing the use of 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 was divided into three main parts and included experimental work on the quality of recycled aggregate and recycled aggregate concrete, a feasibility study on the reuse of concrete waste, production of recycled aggregate using real-scale plant, and quality of recycled aggregate concrete.

This paper presents the results 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 practical aspects for the reuse of construction debris within the LCA.
