A case study on various concrete recycling system in demolition of a thermal power plant was carried out from viewpoint of cost and environmental impact. In the study, one of the life cycle impact assessment method developed by Japanese national project "Life-cycle Impact assessment Method based on Endpoint modeling (LIME)" was introduced for the evaluation of effectiveness of the recycling system compared to only reusing for roadbed gravel and/or backfilling material. In this study CO_2 emission, crude oil consumption, land use for waste disposal and use of natural aggregate are evaluated.

In order to build the recycling system of concrete waste, a primary study for applicability of recycled fine aggregate concrete to the precast concrete products has been carried out. The study results have confirmed that a) the properties of recycled fine aggregate can be improved by the wet grinding treatment, b) the properties of recycled fine aggregate concrete can be improved by steam curing, c) reuse of recycled fine aggregate concrete is highly applicable through property improvement, and d) reuse of recycled fine aggregate concrete is highly effective in view of cost and environment influence. The study results have also proven that the material design of recycled fine aggregate concrete for the precast concrete products can be made by applying the relative quality value method.

In order to apply recycled aggregate concrete produced by the aggregate replacing method to a real structure, the quality control method was investigated, and this paper describes various qualities of the recycled coarse aggregate and recycled aggregate concrete produced by the actual plant. Specifically, the control method of an alkali-silica-reaction and chloride content for recycled coarse aggregate, and the control method of a length change and neutralization for recycled aggregate concrete were considered. Results confirmed that the demand quality of recycled aggregate concrete could be maintained according to the part to be used by the shown quality control method.
