An Experimental Study on the Qualities of Recycled Fine Aggregate and Properties of Mortar Producted by the Dry Manufactured Method

건식 제조방식에 의해 생산된 재생 잔 골재의 품질 및 모르타르 특성에 관한 실험적 연구

Recently, it is increased on the concern for the reuse of waste concrete because of the shortage of natural aggregate and the increase of waste concrete. And recycled coarse aggregate is used variously, but the existing wet method producted recycled fine aggregate has problems like the high price facilities, the long time progress of the work and recycled fine aggregate of poor. The aim of this study is to investigate the possibility of the method of dry producted high qualities recycled fine aggregate. The results of this study have shown that the possibility of the method of dry is certificated as the qualities of recycled fine aggregate satisfied the KS and the compressive strength of mortar was similar to plain.
