Embodiment 1

[0032] First crush the blocky quicklime into small pieces with a diameter of less than 1.8cm, then send it into a ball mill to grind to 170 mesh and the sieve residue is less than 10% for later use, then mix high-calcium fly ash, ordinary fly ash, gypsum and water by Parts by weight in 20m after electronic batching 3 The slurry is stirred in the ground pit to make slurry for later use, and then quicklime, cement and aluminum powder are added to the aforementioned slurry in parts by weight, and the slurry is obtained after being stirred evenly. The slurry is poured into the mold at a temperature of 45°C. Stand still for 2 hours after pouring is completed to obtain green body. After pouring, the remaining slurry is stored in 50m 3 Reserved in the slurry storage tank. Place the green body sideways so that the green body is 4800mm long, 600mm wide, and 1200mm high, using a cutting steel wire with a diameter of 0.1mm. After turning over, longitudinal cutting, and cross cutting, ...

Embodiment 3

[0037] First crush the blocky quicklime into small pieces with a diameter of less than 1.8cm, and then send it to a ball mill to grind to 190 mesh with a sieve allowance of less than 10% for later use, then mix high-calcium fly ash, ordinary fly ash, gypsum and water into Parts by weight in 20m after electronic batching 3 The slurry is stirred in the ground pit to make slurry for later use, and then quicklime, cement and aluminum powder are added to the aforementioned slurry in parts by weight, and the slurry is obtained after being stirred evenly. The slurry is poured into the mold at a temperature of 52°C. Stand still for 2.5 hours after pouring to obtain green body. After pouring, the remaining slurry is stored in 50m 3Reserved in the slurry storage tank. Place the green body sideways so that the green body is 4800mm long, 600mm wide, and 1200mm high. Using a cutting steel wire with a diameter of 0.14mm, the steel wire does not move after turning over, longitudinal cutti...

Abstract

The invention discloses an aerated concrete building block and a manufacturing method thereof. According to the aerated concrete building block, fly ash and gypsum are taken as main raw materials. The aerated concrete building block contains the following raw materials in parts by weight: 60-75 parts of high-calcium fly ash, 4-15 parts of ordinary fly ash, 5-8 parts of gypsum, 13-16 parts of lime, 10-13 parts of cement, 0.07-0.10 part of aluminum powder and 43-46 parts of water. The manufacturing method of the aerated concrete building block mainly comprises the following steps of: (1) preparing materials; (2) pouring slurry; (3) standing; (4) cutting; and (5) carrying out autoclaved curing. The aerated concrete building block and the manufacturing method of the aerated concrete building block have the beneficial effects that the quality of the aerated concrete building block meets national standards, and the durability, crack resistance and frost resistance are improved; and the manufacturing method is scientific and reasonable, the effective utilization of the high-calcium and ordinary fly ashes is promoted, the production cost is reduced, and the yield is increased.

Description

technical field [0001] The invention relates to an aerated concrete block and a manufacturing method thereof. Background technique [0002] Autoclaved aerated concrete block, as a new type of wall material, has far more advantages than traditional clay bricks, and has gradually replaced the dominant position of clay bricks, becoming the mainstream product of building materials. The unit volume weight of autoclaved aerated concrete blocks is one-third of that of clay bricks, the thermal insulation performance is 3-4 times that of clay bricks, the sound insulation performance is twice that of clay bricks, and the impermeability performance is 3 times that of clay bricks. Its fire resistance is more than double that of reinforced concrete, and its fire resistance is 6-8 times that of reinforced concrete; its construction characteristics are also very good, not only can produce various specifications in the factory, but also can be sawed, planed, drilled and nailed like wood; du...
