BASIC STUDY ON CONSTRUCTING TIDAL FLAT USING MOLTEN SLAG

Abstract

 In recent years, recycled materials such as steel slag in marine areas has been used as a replacement material to preserve coastal areas. Molten slag, which is obtained by melting general wastes, has little experience in use at coastal area and does not have hydraulicity such as steel slag, so it can be used for constructing artificial tidal flats. In this study, the performance of the molten slag has been studied through comparative experiments to create artificial tidal flats using different materials such as molten slag, silica sand, and mixtures. The results of the study showed that the pH value in the tank using molten slag was not increased, which was different from that of steel slag. The adsorption of phosphorus was observed, indicating the possibility of using molten slag as a replacement material for constructing artificial tidal flats.
