The invention discloses an anticorrosion aerated brick, which is characterized by being made of the following raw materials by weight part: 14-16 of quicklime, 24-26 of fluorite slag, 1-2 of hydrogen peroxide, 8-9 of cement, 0.2-0.4 of ammonium bisulfite, 0.4-0.6 of salt cake, 10-12 of urban road waste cement road slag, 2-4 of zirconia, 6-8 of fly ash, 5-8 of acrylic fiber, 1-3 of magnesium aluminometasilicate, 7-9 of dibenzylidene sorbitol, 4-7 of perfluoroalkylethyl acrylate, 0.3-0.7 of N-vinyl pyrrolidone, 6-8 of olive oil, 0.3-0.5 of citronella grass, 0.2-0.6 of folium artemisiae argyi, 3-5 of an additive, and a proper amount of water. The aerated brick made by the invention has good anticorrosion effect and good wear resistance, can effectively prevent external force and internal stress damage and resist acid liquor corrosion or flue gas scouring, can effectively prolonging the service life of the matrix, and reduces energy consumption. Meanwhile, by optimizing the formula materials, cracks on a green body are reduced, the qualified rate and the compressive strength of the finished product are excellent.
