Resently, sargassum honeri, which has flown into the Korean coast, has become a serious problem due to the serious damage to domestic aquaculture and fishery. The purpose of this study is to utilize sargassum honeri containing alginic acid as a natural polymer material in cement mortar for repairing structures. The experimental results show that the flow of mortar tends to decrease as the incorporation rate of biopolymer increases.
