| 要旨 | Wet carbonation of Ca(OH)2 and hydrated cement paste granules (HCPG) was performed using aqueous amine systems of EDA, AEEA (diamines), and MDEA (tertiary monoamine). Carbonation performance, assessed by solid CaCO2 formation, showed lower carbonate formation for EDA and AEEA in Ca(OH)2 compared to the control. However, EDA and AEEA shows higher carbonate formation than MDEA in the HCPG system, with comparable efficiency per 1 mol of nitrogen despite the diamine structure. additionally, EDA and AEEA significantly affected the HCPG structure during carbonation. |
