CEMENT-BASED COMPOSITION, METHOD FOR PRODUCING CEMENT-BASED COMPOSITION, AND METHOD FOR RECOVERING CARBON DIOXIDE
To provide: a recyclable cement-based composition having improved carbon dioxide-absorbing capacity; and a technology capable of regenerating a carbon dioxide-absorbing performance of a cement-based composition and preventing carbon dioxide from being released into an atmosphere during production or regeneration of carbon dioxide absorption capacity.SOLUTION: A cement-based composition comprises a carbon dioxide-absorbing material. The carbon dioxide-absorbing material has properties of absorbing carbon dioxide under a normal temperature and pressure condition and releasing the absorbed carbon dioxide when heated to 100 to 300°C. The carbon dioxide-absorbing material is either potassium carbonate or sodium ferrite.SELECTED DRAWING: Figure 1
【課題】 二酸化炭素吸収能力が向上し、再生利用が可能なセメント系組成物の提供、セメント系組成物の二酸化炭素吸収性能を再生回復することが出来て、製造時或いは二酸化炭素吸収能力再生時において二酸化炭素が大気中に放出されることを防止出来る技術の提供。【解決手段】 二酸化炭素を吸収する材料を含有し、二酸化炭素を吸収する材料は常温常圧で二酸化炭素を吸収し１００～３００℃に加熱すると吸収した二酸化炭素を放出する性質を有する。二酸化炭素を吸収する材料は炭酸カリウム、ナトリウムフェライトの何れかである。【選択図】図１
