The Application of Converts Slag for Vertical Drains

제강슬레그의 연직배수재로서의 활용에 관한 연구

In this study, it was to investigate the possibility to use the converts slag, by product in producing steel as a substitute material with sand that is used fur a civil construction materials, in developing techniques to use converts slag to improve soft clay ground. To do this, it was investigated the physical and mechanical properties of the converts slag as a civil construction material. For this, cylindrical cell consolidation with a single vertical drains and large scale soil box test were performed. Through large scale soil box test, the applicability of the converts slag to the present vertical drain techniques which is dependent on sand and plastic drains was studied. As a result of that, it was found that the shape of inserted drains was maintained after completing a consolidation process of a soft clay with slag drains. In addition, we could find that the slag drains showed the similar results with sand drains in soft clay by analyzing the effect of acceleration of consolidation.
