Abstract

The invention discloses an aerated brick. The aerated brick is prepared from the following raw materials by the conventional process for preparing the aerated brick: 30 to 35 weight parts of iron ore tailing, 5 to 10 weight parts of cement, 10 to 15 weight parts of quick lime, 5 to 10 weight parts of modified nano powder, 5 to 10 weight parts of broken glass powder, 3 to 5 weight parts of gypsum, 0.05 to 0.1 weight part of aluminum powder, 0.002 to 0.008 weight part of Chinese honey locust powder, 0.03 to 0.08 weight part of tea seed cake powder, 0.003 to 0.005 weight part of soda ash, 0.5 to 0.8 weight part of calcium stearate, 0.3 to 0.5 weight part of zinc stearate, 0.01 to 0.03 weight part of calcium chloride, 0.05 to 0.1 weight part of white emulsion and an appropriate amount of water. By adding nano mineral powder, the volume weight of the brick, and the energy consumption are reduced; the brick is high in thermal insulation performance and sound insulation performance; and compared with the conventional aerated brick, the aerated brick has the advantage that the thermal insulation performance and the sound insulation performance are improved obviously. Meanwhile, the raw materials are mixed according to an optimized formula; and the intensity and the freezing resistance of the brick are improved obviously.

Description

technical field [0001] The invention relates to the field of bricks, in particular to an aerated brick. Background technique [0002] Air-entrained concrete is a new type of wall building material. It is unique in that it is a very lightweight new type of building wall material for thermal insulation. The air-entrained concrete technology started a hundred years ago, and my country's technology started relatively late, 40 years behind foreign countries. However, the development of my country's air-entrained concrete industry is indeed very rapid. Now the technical level of domestic air-entrained concrete technology has reached the international advanced level. [0003] The biggest advantage of aerated concrete is that it saves land resources and does not need to waste a lot of cultivated land, and its raw materials come from a wide range of sources. Ash sand, slag, iron ore tailings and coal gangue are all raw materials for aerated concrete. Moreover, the performance chara...
