MATERIAL FOR SEAWATER ECOSYSTEM PRESERVATION AND RED-TIDE PREVENTION

摘要

A seawater ecosystem is preserved and a red tide is prevented by recycling steel by-products generated in a steel iron industry. A seawater ecosystem preservation and red tide prevention material includes: SiO2Of 15~35%; CaO of 30~50%; Al2O3Of 2~15%; MgO of 3~10%; MnO of 1~6%; and FeO of 1~18%, which are obtained by pulverizing and aging bulky slags which are the steel by-products generated in a furnace process and a steel making process in the steel iron industry. The seawater ecosystem preservation and red tide prevention material is scattered into the polluted sea to preserve the ecosystem and prevent the red tide.
