Method for preparing composite wallboard from manganese mine waste residue processed by magnesium oxide
The invention provides a lightweight concrete product. The product is prepared by the following steps: magnesium oxide is used as a main gel material, a manganese mine industrial waste residue is used as a filling material, an aqueous solution of magnesium sulfate is used as a blender, and a composite mixed slurry prepared from industrial glue, a modifier and a short fiber as reinforcing materials is added, protein composite foam is mixed, blending, casting and moulding, and maintenance are carried out to obtain the lightweight concrete product. The product can be used as a composite material of a reinforced lightweight composite insulated external wall panel, various insulated modules and building blocks. A test shows that the product has the advantages of good compressive strength, surface density, bending resistance, damage bearing, low heat conduction coefficient, good flame resistance and the like. A lot of manganese mine industrial waste residues are used in the preparation process, and the product is an ideal energy saving and environmental protecting building material. Modified magnesium-oxysulfate-citric is used as a main gel material, and the product has the advantages of low thermal expansion, bending resistance, deformation resistance, cracking resistance, water resistance, moisture regaining resistance, impermeability, scumming resistance, excellent incombustibility, freeze thaw resistance, good impermeability and wear resistance.
