Abstract

In this study, the steel slag was immersed in CO2 nano-bubble water by Electric arc funace it was accelerated aging was reviewed through XRD analysis. The main minerals of the electric furnace oxidized slag were spinel and gehlenite, and there was no change with the number of CO2 nano-bubbles. Minerals such as larnite, calcio-olivine, agnetite, calcite, and spinel were distributed in electrically reduced slag, and the content of calcite more than doubled with CO2 nano-bubble immersion. Therefore, it is judged that the acceleration aging of Electric arc funace reduced slag is effective according to the immersion of CO2 nano-bubble.
