Abstract

This study proposes a unique technique for improving qualities of concrete with recycled concrete coarse aggregate; a decompression and rapid release (DC-RR). In this paper, experimental studies with full scale specimens are described on the effectiveness of the DC-RR procedure on the performances of concrete structures with recycled concrete coarse aggregate, such as core strengths of columns, defections of slabs and crack widths of walls. It was found that, by applying the DC-RR procedure, the performances of full scale concrete specimens with recycled coarse aggregate were much improved and evaluated as almost equal to those with natural coarse aggregate.
