| Outline of Final Research Achievements |
Steel-making slag concrete (SSC) is an environmental-friendly material made of steel-making slag, ground granulated blast-furnace slag, coal fly ash, and so on. Special emphasis should be placed on that the steel-making slag can be a supply source of iron which is necessary for the growth of seaweed. In the present work, the applicability of POSSC where hot-metal pretreatment slag was used as iron-supply source into seaweed bed block was experimentally investigated. The following conclusions can be drawn: (1) The compressive strength and the iron elution velocity of POSSC, that are necessary for material design, can be predicted as a function of total void ratio of POSSC; (2) Replacing 2% of hot-metal pretreatment slag volume makes it possible for the iron-supply capacity of POSSC to be significantly improved, without sacrificing its compressive strength.
