Abstract

In this study, in CO2 sequestration was carried out through pressure carbonation for concrete slurry water to realize carbon neutrality in the cement industry. As a result of the experiment, it was confirmed that as the pressure of CO2 increased, the pH decreased and the amount of CaCO3 produced increased. However, despite the CO2 pressure of 5 bars, the carbonation reaction for 10 minutes alone did not proceed completely.
