| Research Abstract |
The purpose of this study is to develop the method for the early recovery of the biodiversity in the oligotropical coastal area. It is of importance in the recovery of the biodiversity to make kelp forest grow in the concerned area. In order for it, sufficient nutrient is required as well as the proper seedbed.
Hence, in this study, granulated fertilizer, which contains nutrient, such as nitrogen, phosphorus and iron, is coated by the special polymer, and then, is mixed into the porous concrete in order to provide seedbed and nutrient simultaneously. The physical and chemical properties of porous concrete with granulated fertilizer are discussed.
Then brief note is appended to describe the method to select the place of implantation and to control the implantation with the aid of the artificial satellite to measure the chlorophyll concentration on sea surface.
Research results from 2001 to 2005 are as follows.
1)Manufacturing method and rheological properties of binder and also segregation of fresh porous concrete (POC.)
2)Physical and chemical properties of porous concrete (POG)., and clarified the durability of freezing and thawing, washout test by water and abrasion by grain in sea
3)Properties of POC mixed with fertilizer and converter slag in seawater.
4)Seaweed adhesion onto POC mixed fertilizer and converter slag.
5)Water purification performance of POC.
6)Properties and seaweed adhesion of POC using the recycled material.
7)Chlorophyll concentration of sea surface and consistency of data measured from satellite observation.
