Energy-saving environment-friendly non-burnt brick and preparation method thereof

Abstract

The invention discloses an energy-saving environment-friendly non-burnt brick and a preparation method thereof. The non-burnt brick is characterized by being prepared from the following raw materialsin parts by weight: 10 to 40 parts of red plain soil, 10 to 40 parts of construction waste, 4 to 10 parts of cement, 10 to 20 parts of lime, 3 to 5 parts of silica fume, 2 to 4 parts of sodium chloride, 1 to 3 parts of polyacrylamide, 5 to 8 parts of glutinous rice, and 1 to 3 parts of gel. According to the invention, the land occupation problem by construction waste is solved, also a plurality ofwaste materials and building debris are used to replace mud sand, pebbles and the like, so that environmental damage caused by excessive exploitation caused by use of mud sand is avoided, at the sametime reuse of waste is realized, comprehensive utilization, turning waste into treasure and turning harm into profit are realized, resources are effectively utilized and ecological environment is protected; and meanwhile, the problem of air pollution caused by discharge of non-burnt bricks is solved, environment is protected, and production costs are saved, and the non-burnt brick has good economic benefits and has good application value.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an energy-saving and environment-friendly burn-free brick and a preparation method thereof. Background technique [0002] Traditional fired bricks mainly use clay as raw material. However, with the continuous development of the construction industry, the demand for bricks is gradually increasing. The existing clay resources can no longer meet the needs of bricks. In addition, my country's continuous strengthening of environmental protection , the baked bricks will release a large amount of harmful gases during the firing process, such as carbon monoxide, carbon dioxide, hydrogen sulfide, etc., which will pollute the environment and endanger human health. Bricks that are widely used are made of soil, sand, pebbles and water as the main raw materials. With the increasing demand for bricks, many brick factories have made great efforts to expand the production sc...

[0002] Traditional fired bricks mainly use clay as raw material. However, with the continuous development of the construction industry, the demand for bricks is gradually increasing. The existing clay resources can no longer meet the needs of bricks. In addition, my country's continuous strengthening of environmental protection , the baked bricks will release a large amount of harmful gases during the firing process, such as carbon monoxide, carbon dioxide, hydrogen sulfide, etc., which will pollute the environment and endanger human health. Bricks that are widely used are made of soil, sand, pebbles and water as the main raw materials. With the increasing demand for bricks, many brick factories have made great efforts to expand the production scale and increase output. The environment has been destructively developed, resulting in excessive mining of mud, sand and pebbles in many brick production bases, which seriously affects the natural environment;

[0003] At present, the production of self-insulating concrete composite blocks only needs to use about 40% waste coal ash as admixture, cement, lime, gypsum, and adhesives as cementing materials; gravel, sand, and ceramsite as aggregates, and groundwater Or tap water as the mixing liquid, made of organic or inorganic chemical raw materials as the activator, and the density of the finished product is above 800kg / m3. This scheme disposes of a certain amount of industrial waste (about 40%), and consumes a large amount of industrial products and parts Non-renewable resources have higher costs
