석재 가공시 발생한 석분슬러지의 콘크리트 혼화재료로의 활용 = Utilization of Stone Sludge Produced by Stone Block Manufacturing Process as Concrete Admixtures

다국어 초록 (Multilingual Abstract)

The stone sludge produced during the manufacturing process of stone blocks is considered as one of industrial waste materials. This stone sludge are managed to either burying under the ground or stacking in the yard, but this disposal process is required an extra costs. The stone sludge disposal like burying or stacking also cause environmental pollutions such as ground pollution and subterranean water pollution. Thus, this study was conducted to explore the possibility of recycling of stone dust sludge as a concrete mixing material in order to extend recycling methods and to solve the shortage of aggregate caused by recently increased demand in construction. Based on the experiment results on various ratios of cement to stone sludge content, the compressive strengths of concrete were recorded in the range of 20~30N/mm2. The results did not show any decrease in compressive strength due to the stone dust content. It can be concluded that the stone sludge produced by stone block manufacturing can be sufficiently recycled as one of concrete mixing materials in the aspect of compressive strength.
