- Synopsis
- A large steel-making slag blocks were produced by carbonation process of steel-making slag. It was confirmed that these blocks were porous and the surface was covered with calcium carbonate. In this study, the possibility of using these blocks as a seaweed bed was investigated. As a result, these blocks were equal to concrete in the material characteristic and the hydracteristic, and excellent in the algae creation effect. It was shown that the steel-making slag blocks using carbonation process were useful materials for marine plant cultivation beds and artificial reefs from these results.
