THEORETICAL RESEARCH AND APPLICATION OF CARBONATION AND MICROBIAL MINERALIZATION OF STEEL SLAG
China is a major emitter of carbon dioxide,therefore,energy conservation and carbon reduction in high carbon emitting industries such as cement,steel,and chemicals are imperative.Steel slag carbonation is a low-carbon technology that utilizes metallurgical solid waste converter slag to absorb and capture greenhouse gas carbon dioxide.It can not only achieve carbon dioxide capture and consumption,but also stabilize steel slag through carbonation reaction,improving the performance of steel slag building materials.Therefore,the application prospects of steel slag carbonation technology are relatively broad.Based on this,a detailed introduction was given to the research,development,and existing problems of steel slag carbonation technology at home and abroad.Further analysis was conducted on the cutting-edge microbial carbonation technology for steel slag and its application.It is proposed to strengthen the development of low input and high effect carbonation efficiency improvement technology,such as steel slag microbial carbonation technology,to simultaneously improve the efficiency and rate of steel slag carbonation while ensuring the gel characteristics of carbonated steel slag,which will help to realize the resource utilization of steel slag and carbon reduction.
