Abstract

Biofouling on a steel slag hydrated matrix using steel-making slag as the aggregate and ground granulated blast-furnace slag as the main binder was investigated in enclosed coastal areas, and was compared with that on concrete and a natural rocky shore. The steel slag hydrated matrix tended to display larger microalgal density and diversity than concrete from the initial period at the start of the test, confirming that microalgae readily grow on the steel slag-based material. At a seawall where large-scale works were executed, the biofouling on the steel slag hydrated matrix was equal or superior to that on the natural rocky shore. Based on these results, the steel slag hydrated matrix was judged to be excellent in biofouling performance.
