Utilization of Waste Concrete as Vertical Drain Material

연직배수재료로 폐콘크리트 활용에 관한 기초연구

This paper presents the utilization of waste concrete as vertical drain material. The materials used as vertical drain material were the waste concrete, obtained from the demolished apartments or concrete structure and sand. In this study, laboratory model test was performed to investigate settlement and bearing capacity between sand compaction pile and waste concrete compaction pile. The results of laboratory model test showed that the improvement efficiency of soft ground by waste concrete compaction pile was better than sand compaction pile.
