Embodiment Construction

[0024] A method for preparing air-entraining hollow bricks by using ceramic waste is carried out according to the following steps:

[0025] (1) Mix the raw materials according to the following parts by weight on a dry basis:

[0026] 65 parts of ceramic waste after crushing

[0027] 25 parts of river sand

[0028] Quicklime 10 parts

[0029] Cement 8 parts

[0030] 1.5 parts of lignocellulose

[0031] Redispersible latex powder 4 parts

[0032] (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 0.02% of the dry basis of the mixed raw materials, add methyl cellulose ether to 0.3%, and add epoxy linseed oil to 2% , add gypsum to 20% of the mass of quicklime, add Pingping to 14% of the weight of aluminum powder;

[0033] (3) Put the slurry stirred in the above step (2) at a temperature of 60-80°C, and foam for 30-40 minutes;

[0034] (4) The foaming slurry in the above ...

Abstract

The invention discloses a method for preparing aerated bricks by utilizing ceramic waste, and the method comprises following steps of (1) mixing raw materials according to the following dry basis in parts by weight: ceramic waste after being ground, quicklime, cement and the like; (2) placing water according to 85 to 95 percent of the mass of the mixed raw material dry base in step (1), placing waste aluminum powder according to 0.01 to 0.03 percent of the mass of the mixed raw material dry base, placing plaster according to 9 to 11 percent of the mass of quicklime, and placing peregal which is 1 to 4 percent of the mass of aluminum powder; and (3) the slurry after being stirred in step (2) is foamed for 30 to 40 minutes under the temperature of 60 to 80 DEG C. Due to the adoption of the method, the consumption of ceramic waste is vast, energy conservation and environmental protection can be realized, the environmental pollution problem caused by the stacking treatment of the ceramic waste can be alleviated, and simultaneously new raw material source can be supplied 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 from ceramic waste. Background technique [0002] With the rapid development of social economy and ceramic industry, ceramic industry waste is increasing day by day. It not only puts great pressure on the urban environment, but also limits the development of urban economy and the sustainable development of the ceramic industry. Therefore, the treatment and utilization of ceramic industry waste Very important. At present, the degree of treatment and utilization of ceramic industry waste in my country is relatively low, and funds are in short supply, resulting in a large amount of waste slag occupying cultivated land and polluting water and air. Especially in the past 20 years of rapid development, with the increase of output in the ceramic industry, the amount of waste is increasing. According to incomplete statistics: only the Fo...
