- Synopsis
- Application example of recycled aggregate concrete is extremely few even though many studies on quality of recycled aggregates for the structural concrete have been conducted so far. Based on several experimental investigations, therefore, we have attempted an application of low quality recycled coarse aggregates, which are made from demolished concrete of an old hydroelectric power plant, to renovation work of the power plant. In this paper, both the characteristics of the recycled aggregate concrete and cost performance of this project are reported.

- recycled aggregate concrete, low level treatment process, hydroelectric power plant, percentage of water absorption, drying shrinkage, self compacting concrete
