Resource utilization method for capturing carbon dioxide

The invention relates to a resource utilization method for capturing carbon dioxide, in particular to a method for realizing utilization and mineralization storage of carbon dioxide by directly adding an absorbent for absorbing carbon dioxide into a cement-based material. The absorbent absorbs carbon dioxide and then is added into the cement-based material, part of the absorbed carbon dioxide is desorbed in a hydration environment of the cement-based material and reacts with Ca < 2 + > in a solution to generate calcium carbonate, and mineralization and storage of the carbon dioxide are achieved. The absorbent for absorbing carbon dioxide is directly utilized, so that energy consumption caused in the desorption process of the conventional absorbent is avoided, and'zero emission 'or even'negative emission' of carbon dioxide in the process is realized. 本发明涉及涉及一种捕集二氧化碳的资源化利用方法，具体涉及一种直接将吸收二氧化碳的吸收剂加入水泥基材料实现二氧化碳的利用及矿化封存方法。吸收剂吸收二氧化碳后加入至水泥基材料中，部分吸收的二氧化碳在水泥基材料的水化环境中解吸，与溶液中的Ca2+反应生成碳酸钙，实现二氧化碳的矿化封存。对吸收二氧化碳的吸收剂直接利用，避免了常规吸
