Zusammenfassung: | The invention particularly relates to an aluminum-based solid waste porous material and a preparation method thereof, and belongs to the technical field of solid waste comprehensive utilization, the porous material comprises the following raw materials by mass: 40-70% of aluminum ash, 0-40% of red mud, 0-20% of carbon residue, and 20% of kaolin. Through mutual cooperation of the raw materials, various components in the aluminum ash are effectively utilized, high-value utilization of aluminum industrial waste can be achieved, fluoride in the aluminum ash assists aluminum oxide and silicon oxide in the aluminum ash and red mud to react to form a ceramic phase, mullitization reaction of the raw materials is accelerated, and a matrix of the porous material is formed; aluminum nitride in the aluminum ash can cooperate with the carbon residues to assist foaming, and a porous condition of the porous material is provided; components in the red mud and the aluminum ash can play a role in fixing fluorine; the kaolin se |
