Preparation method of building product of coal ash-based foam material consolidated carbon dioxide
The invention relates to the technical field of preparation of building products from solid wastes, and discloses a preparation method of a building product with coal ash-based foam material consolidated with carbon dioxide, which comprises the following steps: step 1, taking the solid wastes of a thermal power plant as main raw materials, and stirring to prepare a mixture; 2, adding an alkaline activator and a foam stabilizer into the mixture obtained in the step 1, and mixing to obtain slurry; 3, a foaming agent is added into the slurry obtained in the step 2, stirring and mixing are conducted, and then a formed blank is obtained through forming and curing; and 4, carbonizing the molded green body obtained in the step 3 to obtain the building product. The preparation method of the building product consolidated with carbon dioxide by the fly ash-based foam material has the advantages of high carbon sequestration efficiency, short carbon sequestration time, low energy consumption and high compressive strength of the product.
本发明涉及固废制备建筑制品技术领域，且公开了粉煤灰基发泡材料固结二氧化碳的建筑制品的制备方法，包括如下步骤：步骤一：将火电发电厂固废作为主要原料搅拌制成混合物；步骤二：在步骤一得到的混合物中加入碱性激发剂和稳泡剂混合得到浆料；步骤三：在步骤二得到的浆料中加入发泡剂并搅拌混合后，再经成型、养护获得成型坯体；步骤四：将步骤三得到的成型坯体经碳化后得到所述建筑制品。该粉煤灰基发泡材料固结二氧化碳的建筑制品的制备方法，具备固碳效率高、固碳时间短、能耗低和产品抗压强度高的优点。
