摘要：

Application of the recycled aggregate is a promising technology for resource saving and low environmental impacts, which is more effectively performed when recycled fine aggregate is used in addition to recycled coarse aggregate. Use of the recycled fine aggregate for the upper structures, however, shows minor progress because of the trade-off in aggregate quality and emission of fine particles. Two effective technologies, production of energy saving mid-quality recycled aggregate and high-quality recycled fine aggregate, presented in this paper enabled the application of the mid-quality recycled aggregate to the upper structure for the first time in Japan.
