A Study on the Properties of Porous Concrete For Kelp Forest Regeneration Using Cement Coating Granular Fertilizer

시멘트 코팅 입상비료를 이용한 조장조성용 포러스콘크리트의 특성에 관한 연구

The Purpose of this study is to develope the method for early recovery of the biodiversity in the oligotrophical costal area. The result of this study, the dissolution ratio is superior in the case which the cement coating thickness of the granular fertilizer is below 1mm. From the failure-side it is judged with the fact that appropriate to use the separate charging method and vibration compaction method. For the cases of the mixing ratio of cement coating granular fertilizer, there was not any clear tendency for the change of the strength up to 20$\%$ of the mixing ratio. However, at the 30$\%$ mixing ratio, decrease of the strength was noticed. So it can be concluded that the stability can be achieved in the range of 20$\%$ and below.
