The invention discloses a method of preparing aluminum oxide-silicon carbide compound porous ceramic by aluminum-silicon industrial waste residues. The primary raw materials comprise industrial waste residues, carbon powder, a pore forming substance and an adhesive. The aluminum oxide-silicon carbide compound porous ceramic is prepared by the following steps of mixing, drying, forming and sintering to obtain a final product. Treatment and high additional value utilization of the industrial waste residues are achieved. The prepared porous ceramic is remarkable in performance, and can be applied to the fields of filtration, sound isolation, heat isolation, fire fighting and the like. The method is simple in process flow and convenient for industrialized promotion; and the cost is good to control and the method has extreme economical value.

The invention discloses a fiber foamed concrete and a preparation method thereof. The fiber foamed concrete comprises the following raw materials in parts by weight: 5290 parts of cement, 4965 parts of water, 1.361 part of foaming solution, 1.2964 part of fly ash and 10 parts of fiber. The preparation method comprises the following steps: proportionally weighing the components; sequentially adding the cement and fly ash into a stirrer, proportionally weighing the water, uniformly stirring the mixture by the stirrer, and adding the fiber; preparing and adding the foaming solution; gradually adding the foam into the mixture, and continuously stirring until all the components are uniformly mixed; pouring the mixture into a mold on which lubricating oil is brushed, and curing in a curing chamber; after 24 hours, removing the mold; and respectively curing for 3 days, 7 days and 28 days for experimental detection. The fiber foamed concrete has the advantages of favorable thermal insulation property, favorable compression resistance and favorable bending resistance, and is applicable to a railway bed strengthening layer.
