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 the like; meanwhile, spontaneous heating generated in the mineralization process is reasonably utilized, and the carbon sequestration effect of mineralized products is improved.
本发明涉及C04B领域,具体为一种钢铁行业固废及二氧化碳协同制备建筑材料的方法,所述方法以钢铁行业固废为原料,通过控制成型方式得到坯体,坯体在通有二氧化碳的烟气密闭环境中进行矿化反应,制得成品建筑材料。本发明针对现有钢渣制品存在密度高、应用场景少、工艺净减排较低、矿化程度低的问题,设计提出了一种钢铁行业固废及二氧化碳协同制备建筑材料的制备方法,通过成型方式的改变、原料配方及相关工艺的优化等方法调控试块密度,进而保证矿化效率,同时合理利用矿化过程产生的自发热,提高矿化产品的固碳效果。
