| Research Abstract |
The study presents the CO2 fixation properties of steel slag containing calcium, and proposes a geotechnical application for the formation of a sound material-cycle society and a low-carbon society. In order to investigate the properties of CO2 fixation, CO2 fixation test with vented constant flow was conducted. As a result, when the CO2 concentration 4500 mg/L was vented in a specimen by 0.05 L/min, the aging steelmaking slag were fixed CO2 of 0.03 g-CO2/g-slag. In addition, non-aging steelmaking slag fixed CO2 of 0.04 g-CO2/g-slag. Fixed amount of CO2 was about 20% water-soluble calcium with each of the steelmaking slag. Therefore, showing a method of predicting the amount of fixed CO2 from the elution amount of calcium.
