An Experimental Study on the Reuse of Recycling Water of Reacy Mixed Concrete such as Concrete Water (I) -A Case Study on the Mortar-

레미콘 회수수의 콘크리트 용수로써의 재활용에 관한 실험적 연구 (I) -모르터 적용실험을 중심으로-

This study is designed for analyzing the mechanical properties of cement mortar with kind of water, sludge content for the water, mixing proportion and open time of recycling water. And this study is aimed for presenting the reference data in practical use. For the results of this study, the flow properties of fresh mortar and the strength of compresive of hardened mortar is increased until the sludge content 4.5~6.0, but is decreased after the sludge content of that.
