A Fundamental Study on CO₂ Sequestration of Concrete Slurry Water by Pressure Carbonation

가압 탄산화를 통한 레미콘 회수수의 CO₂ 고정화에 관한 기초적 연구

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.
