The purpose of this preliminary study is to characterize stone powder granulated with cement for the remediation of an organically rich sediment and the control of nutrient balance in a water column. The material used contained SiO2, Al2O3, K2O, CaO, CO3, Fe2O3, MgO, TiO2 and trace elements with quartz and aluminum silicate as the main phases. An increase in the pH of seawater due to cement was observed with the material addition, which was effective for the remediation of the acid-rich sediment in coastal seas. Phosphate and silicate were released into seawater and the growth of S. costatum was maintained with the material addition. Thus, results of this preliminary study support the notion that the application of granulated stone powder may have potential advantages for the remediation of the acid-rich sediment and the control of the balance of nutrients in seawater.
