Active calcium silicate-containing high-strength aerated brick and preparation method thereof
The invention discloses an active calcium silicate-containing high-strength aerated brick which is prepared from the following raw materials in parts by weight: 2-4 parts of volcanic ash, 1-2 parts of sodium silicate, 5-8 parts of active calcium silicate, 0.1-0.3 part of sulphobetaine, 10-14 parts of mineral cotton, 7-9 parts of gypsum, 50-60 parts of coal ash, 6-7 parts of aerated powdered aluminum, 8-9 parts of cement, 6-8 parts of coal slime, 9-11 parts of quick lime, 9-11 parts of modified walnut shell, 0.2-0.4 part of dicumyl peroxide, 1-2 parts of ethylene vinyl acetate copolymer and a proper amount of water. According to the aerated brick disclosed by the invention, the active calcium silicate and modified volcanic ash are used, the reinforcing effect is good, and the strength, wear resistance and water resistance of the aerated brick are improved; due to the use of the mineral cotton, the breaking strength, fire resistance, heat retaining property, sound insulation and dimensional stability of the aerated brick are improved; and moreover, due to the use of modified walnut shell, the heat insulation effect is enhanced, the water resistance is high, the weight is alleviated, the anti-seismic property is improved, and the water reducing effect is good.
