AB - The purpose of this study was to figure out the impacts of iron oxide types and dosages to bloating whenproducing artificial lightweight aggregates by utilization of recycled resources such as bottom-ash, reject-ash and dredgedsoil. In order to figure out chemical characteristics of raw materials, XRD and XRF analyses were performed. 50 wt% ofdredged-soil, 15 wt% of bottom-ash and 35wt.% of reject-ash were mixed, then the amount of iron oxide was varied at 5to 30 wt% with intervals of 5 wt% with Fe2O3 and Fe3O4 respectively. As molded aggregates were sintered by rapidsintering in intervals of 40oC from 1060oC to 1180oC, specific gravity and water absorption were measured. As a result,the artificial lightweight aggregate with iron oxide of 10~15 vol% showed the lowest specific gravity, and it was identifiedthat the more iron oxide vol% increases, the more specific gravity increases because of liquid phase sintering.
