Abstract

The invention discloses a fluorite slag-containing aerated concrete block. The fluorite slag-containing aerated concrete block is prepared from the following raw materials by the conventional process for preparing the aerated concreted block: 25 to 30 weight parts of coal ash, 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 volcanic rock powder, 3 to 5 weight parts of gypsum, 0.05 to 0.1 weight part of aluminum powder, 0.02 to 0.08 weight part of peregal, 0.03 to 0.08 weight part of oxyparaffin soap, 0.3 to 0.5 weight part of soda ash, 0.5 to 0.8 weight part of bentonite, 0.3 to 0.5 weight part of zinc stearate, 0.01 to 0.03 weight part of aluminum hydroxide, 0.05 to 0.1 weight part of sodium hexametaphosphate and an appropriate amount of water. Nano mineral powder is added, so that the volume weight of the brick, and the energy consumption are reduced; the aerated brick is high in thermal insulation performance and sound insulation performance; compared with the conventional aerated concrete block, the fluorite slag-containing aerated concrete block has the advantages that the thermal insulation performance and the sound insulation performance are improved obviously; 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 concrete block whose raw material contains fluorite slag. 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 arable land, and its raw materials come from a wide range of sources, such as ash, slag, fly ash and coal gangue, etc. are all raw materials for aera...
