초록
본 연구에서는 습식방식 생산시스템의 품질의 대폭적인 향상이 가능한 건설폐기물 재활용을 위한 이물질 분리 선별 장치인 샌드플럭스(Sand Flux)를 개발하기 위한 연구의 일환으로써, 샌드플럭스 장치에서 생산된 순환모래의 기초물성을 평가하고 모르타르의 공학적 특성을 실험 실증적으로 검토함으로써, 본 연구 장치의 성능을 검증하고 하였으며, 본 연구의 기초물성 실험결과, 절건밀도의 경우, RS-II(
This study has shown the tendency to enhance Sand Flux, a device of separating screening the foreign matter, for the recycling of construction waste possible to improve the quality of wet type production system meaningfully as part of research. As a result of experiment on the basic material properties, this study had a tendency to improve the quality and performance significantly in case of absolute surface dried density, 0.08mm sieve throughput, volume of clay lumps, and content of organic foreign matter. In addition, as a result of examining the quality characteristics of mortar, this study has shown the tendency that the flow and compressive strength more increased than the mortar using RS-II by utilizing RS-VI recycled sand produced finally through the device Sand Flux. As for the shrinkage properties, this study has shown the character the generation rate of crack of mortar using RS-IV recycled sand produced finally through the device Sand Flux.
