샌드플럭스 장치를 이용한 순환모래의 생산횟수별 품질변화 및 모르타르의 역학특성에 관한 실험적 연구 = An Experimental Study on the Quality Variation by the Number of Production of Recycled Sand and Mechanics Properties of Mortar using Sand Flux Apparatus

다국어 초록 (Multilingual Abstract)

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.
