Abstract
This study has focused on the possibility for recycling of tailings from the Sangdong tungsten mine as powder of superfluidity self-compacting concrete. The experimental tests for slump-flow, time required to reach 500mm of slump flow(sec), time required to flow through V-funnel(sec) and filling height of U-box test(mm) were carried out in accordance with the specified by the Japanese Society of Civil Engineering(JSCE). The result of this study, in case of superfluidity self-compacting concrete mixed with tailings, slump-flow was decreased with increasing mixing ratio. But time required to reach 500mm of slump flow(sec), time required to flow through V-funnel(sec) and filling height of U-box test(mm) were satisfied a prescribed range.
