Method for synergistically preparing building material from solid waste and carbon dioxide in iron and steel industry

The invention relates to the field of C04B, in particular to a method for synergistically preparing a building material from solid waste in the steel industry and carbon dioxide, and the method comprises the following steps: taking the solid waste in the steel industry as a raw material, obtaining a green body by controlling a molding mode, and performing mineralization reaction on the green body in a closed flue gas environment with carbon dioxide to prepare a finished product building material. In order to solve the problems that an existing steel slag product is high in density, few in application scene, low in process net emission reduction and low in mineralization degree, the invention provides a preparation method for preparing a building material from solid waste and carbon dioxide in the iron and steel industry in a synergetic mode, and the density of a test block is regulated and controlled through the methods of changing a forming mode, optimizing a raw material formula and related processes and th
