Summary:To provide an efficient production method that fixes CO2 to cement hydrate in a short time.SOLUTION: The present invention discloses a method for fixing cement hydrate to CO2, the method including a CO2 blowing step in which cement hydrate 11 and water 12 are put into a container 10, and the liquid mixture of the cement hydrate 11 and the water 12 are stirred while CO2 14 is blown into the container 10. In the CO2 blowing step, the CO2 blowing speed is 3600 kg/t h or more and the CO2 blowing amount is 600 kg/t or more.SELECTED DRAWING: Figure 1 【課題】セメント水和物にＣＯ２を短時間で固定化する高効率な製造方法を提供する。【解決手段】ＣＯ２をセメント水和物に固定する方法であって、セメント水和物１１と、水１２とを容器１０に入れ、セメント水和物１１と水１２との混合液を撹拌しながら、容器１０にＣＯ２１４を吹込むＣＯ２吹込み工程を含んでおり、ＣＯ２吹込み工程において、ＣＯ２吹込み速度は３６００ｋｇ／ｔ・ｈ以上、ＣＯ２吹込み量は６００ｋｇ／ｔ以上である。【選択図】図１
