The invention relates to a method for sealing carbon dioxide by inorganic solid waste ceramsite mineralized concrete, which comprises the following steps: preparing inorganic solid waste ceramsite filter balls; preparing an aminated ceramsite filter ball; after the aminated ceramsite filter ball fully absorbs carbon dioxide, a filter ball adsorbing saturated carbon dioxide is obtained; and uniformly mixing and stirring the saturated carbon dioxide adsorption filter balls and cement mortar concrete to prepare a mineralized lightweight concrete test piece. Inorganic solid waste ceramsite filter balls are treated by an amino acid salt solution and/or amino ionic liquid, then are introduced into a high-concentration CO2 environment such as factory chimney gas and the like to adsorb saturated CO2, and then are directly added into concrete as an additive; and the escaped CO2 rapidly mineralizes and maintains the cementing material and is converted into the main component calcium carbonate of the concrete, and the CO2 is converted and sealed.
本发明涉及一种无机固体废弃物陶粒矿化混凝土封存二氧化碳的方法，包括以下步骤，制备无机固体废弃物陶粒滤球；制备氨基化陶粒滤球；氨基化陶粒滤球充分吸收二氧化碳后获得吸附饱和二氧化碳滤球；将吸附饱和二氧化碳滤球与水泥砂浆混凝土混合搅拌均匀制成矿化轻质混凝土试件。本发明通过将无机固体废弃物陶粒滤球进行氨基酸盐溶液和/或胺基离子液体处理后引入至如工厂烟囱气等高浓度CO2环境中吸附饱和CO2后，再通过将其作为添加剂直接加入混凝土中，在水泥拌合水、水化热或者蒸养养护过程中，逸出的CO2快速矿化养护胶凝材料，转化为混凝土的主要成分碳酸钙，对CO2转化和封存。
