Waterproof and corrosion-resistant aerated brick and preparation method thereof
The invention discloses a waterproof and corrosion-resistant aerated brick and a preparation method thereof. The aerated brick is composed of the following raw materials in parts by weight: 70 to 85 parts of fly ash, 15 to 20 parts of quartz sand, 5 to 8 parts of magnesium oxide, 6 to 9 parts of modified macadamia nut shell, 5 to 7 parts of silicon micropowder, 3 to 5 parts of aluminum powder, 3 to 4 parts of sodium silicate powder, 0.8 to 1.2 parts of sulfur powder, 12 to 15 parts of quicklime, and a proper amount of water. The preparation method comprises step of slurry manufacturing, modified macadamia nut shell mixture manufacturing, brick blank manufacturing, brick steaming and curing in a steaming and curing kettle, moulding, and cooling. The invention aims to provide a waterproof and corrosion-resistant aerated brick and a preparation method. The foams in the aerated brick are fine, dense, and discontinuous. The brick has a good waterproof performance, can be used in a damp environment, and is corrosion resistant. The operation of the preparation method is simple and easy.
