The invention relates to a method for sequestering carbon dioxide by inorganic solid waste ceramsite mineralized concrete, which comprises the following steps: preparing inorganic solid waste ceramsite filter balls; preparing aminated ceramsite filter balls; and the aminated ceramsite filter balls fully absorb carbon dioxide Then, the adsorption saturated carbon dioxide filter ball is obtained; the adsorption saturated carbon dioxide filter ball is mixed with the cement mortar concrete to make a mineralized lightweight concrete test piece. In the present invention, the inorganic solid waste ceramsite filter ball is treated with amino acid salt solution and/or amine-based ionic liquid and introduced into a high-concentration CO2 environment such as factory chimney gas to absorb saturated CO2 , and then use it as an additive Directly added to concrete, in the process of cement mixing water, hydration heat or steam curing, the escaping CO 2 quickly mineralizes and cures the cementitious material, converts it into calcium carbonate, the main component of concrete, and converts and stores CO 2 . |
