Problems solved by technology

[0003] For a long time, the comprehensive utilization of urban inorganic waste has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of inorganic waste at home and abroad, due to various technical and economic reasons, most of them have not been put into industrial realization.
[0004] In summary, it has been reported that using urban inorganic waste as auxiliary raw materials to produce cement, wall bricks, and road materials, but it has not been reported that construction waste is used as the main raw material for the production of aerated blocks.

Embodiment Construction

[0023] The method for preparing air-entraining hollow bricks by using urban inorganic waste is carried out according to the following steps:

[0024] (1) Mix the raw materials according to the following parts by weight on a dry basis:

[0025] 50 copies of urban inorganic waste after crushing

[0026] lime 10 parts

[0027] Fly ash 20 parts

[0028] Cement 5 parts

[0029] Redispersible latex powder 3 parts

[0030] (2) According to the above steps (1), add water to 85% of the dry basis of the mixed raw materials, add waste aluminum powder to 0.03% of the dry basis of the mixed raw materials, add gypsum to 9% of the mass of lime, and add flattening to 12% of the mass of waste aluminum powder Add and add 1% of the dry weight of the mixed raw materials to add triacetin;

[0031] (3) Put the slurry stirred in the above step (2) at a temperature of 65-75°C, and foam for 30-40 minutes;

[0032] (4) The foaming slurry in the above step (3) is steam-cured...

Abstract

The invention discloses a method capable of utilizing city inorganic waste to produce an aerated hollow brick. The method comprises the following steps: (1), mixing such materials in dry basis mass as crushed city inorganic waste, lime and coal ash; and (2), according to the step (1), adding water in 85-95 percent of mixed material dry basis, adding waste aluminite powder in 0.04-0.06 percent of mixed material dry basis, gypsum in 9-11 percent lime, and peregal in 1-4 percent of waste aluminite powder. According to the invention, a larger amount of inorganic waste can be used to achieve the purposes of energy conservation and environment protection and relieve the environment pollution caused by processing the inorganic waste piles, and a novel material source is provided for the hollow bricks.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a method for preparing aerated hollow bricks by utilizing urban inorganic waste. Background technique [0002] Inorganic waste refers to the waste of inorganic components in municipal solid waste. It mainly includes sludge and some waste furniture, waste glass, concrete, etc., and also includes a part of fuel waste and domestic dregs. [0003] For a long time, the comprehensive utilization of urban inorganic waste has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of inorganic waste at home and abroad, due to various technical and economic reasons, most of them have not been put into industrial realization. [0004] In summary, it has been reported that the use of urban inorganic waste as auxiliary raw materials to produce cement, wall bricks, and road materials has not been reported, but construction waste has not been r...
