Air-added brick produced by utilizing waste building rubbish and method for processing air-added brick

Abstract

The invention discloses an air-added brick produced by utilizing waste building rubbish and a method for processing the air-added brick. The air-added brick comprises the following raw materials in part by weight: 50 to 60 parts of waste building rubbish, 20 to 30 parts of urban road waste cement road slag, 5 to 8 parts of cement, 10 to 15 parts of ceramsite, 10 to 15 parts of shale, 5 to 10 parts of corundum mullite sand, 14 to 16 parts of quicklime, 4 to 5 parts of gypsum, 0.03 to 0.05 part of aluminum powder, 0.5 to 1 part of modified straw ash, 0.03 to 0.04 part of caustic soda, 0.3 to 0.5 part of hydroxypropyl methyl cellulose and 0.0008 to 0.0012 part of aluminum powder degreasing agent. By using waste as an ingredient of the air-added brick, environment pollution is effectively reduced, waste materials are recycled, the environment is protected; energy consumption is reduced; the air-added brick has higher heat insulation performance and sound insulation performance compared with the conventional air-added brick; and meanwhile, by optimizing a formula and the raw materials, the strength and the freezing resistance are obviously improved.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to an aerated brick produced by using waste construction waste and a processing method thereof. Background technique [0002] Construction waste is solid waste generated during the process of new building, reconstruction, expansion or demolition of buildings. According to different sources of construction waste, it can be divided into construction waste and demolition construction waste. Construction waste, as the name implies, is in The solid waste generated in new construction, reconstruction or expansion projects, and the demolition of construction waste is the construction waste generated during the demolition of buildings; for a long time, the comprehensive utilization of urban construction waste has been a worldwide problem. A lot of research has been done on the comprehensive utilization of construction waste, but due to various technical and economic reasons, most of th...

[0002] Construction waste is solid waste generated during the process of new building, reconstruction, expansion or demolition of buildings. According to different sources of construction waste, it can be divided into construction waste and demolition construction waste. Construction waste, as the name implies, is in The solid waste generated in new construction, reconstruction or expansion projects, and the demolition of construction waste is the construction waste generated during the demolition of buildings; for a long time, the comprehensive utilization of urban construction waste has always been a worldwide problem. A lot of research has been done on the comprehensive utilization of construction waste, but due to various technical and economic reasons, most of them have not been put into industrial realization.

[0003] In summary, it has been reported that using urban construction waste as an auxiliary raw material to produce cement, wall bricks, and road materials, but there is no report on using construction waste as the main raw material for the production of aerated blocks.
