摘要

This paper presents the CO_(2) 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 CO_(2) fixation, CO_(2) fixation test with vented constant flow was conducted. As a result, when the CO_(2) concentration 4500μL_(-CO2)/L was vented in a specimen by 0.05 L/min, non-aging steelmaking slag amount of CO_(2) fixed is the maximum, the value was 0.04 g_(-CO2)/g-slag. The amount of CO_(2) that is fixed in the steelmaking slag was about 20% of water-soluble calcium. Therefore, a possibility that the quantity of CO_(2) fixation could be evaluated was shown from the viewpoint of the mechanism of CO_(2) fixation using the quantity of water-soluble calcium.
