Summary:The invention relates to a method and a device for fixing carbon dioxide by using a cement-based material. According to the method, the temperature of carbon dioxide is finely adjusted within a rangeof 40-200 DEG C, and a cement-based material with an initial void moisture content of 30-100% reacts with the carbon dioxide within the temperature range, so that the carbon dioxide can be quickly fixed within a relatively wide carbon dioxide concentration range and converted into calcium carbonate or magnesium carbonate with stable performance. 本发明涉及一种用水泥基材料固定二氧化碳的方法及装置。本方法通过微调二氧化碳的温度在40℃～200℃范围内，利用初始空隙含水率为30％～100％的水泥基材料与该温度范围内的二氧化碳反应，可以在较宽的二氧化碳浓度范围内迅速固定二氧化碳，转化为性能稳定的碳酸钙或碳酸镁。
