Autoclaved brick manufactured by utilizing construction waste and preparation method of autoclaved brick
The invention discloses an autoclaved brick manufactured by utilizing construction waste and a preparation method of the autoclaved brick. The autoclaved brick consists of the following raw materials by weight percent: 85 to 94 percent of construction waste powder, 0 to 8 percent of lime powder and 6 to 15 percent of a water-soluble macromolecular compound aqueous solution. The construction waste powder is one or more of waste concrete powder, waste brick powder, waste glass powder and waste mortar powder; the lime powder is quick lime powder and slaked lime powder, and the content of active calcium oxide or calcium hydroxide is required to be more than 70 percent; the water-soluble macromolecular compound is at least one of polyvinyl alcohol, hydroxypropyl methyl cellulose, polyacrylamide, sodium polyacrylate and sodium alginate, and the percentage concentration by weight of the water-soluble macromolecular compound aqueous solution is 0.05 to 1 percent. The autoclaved brick has the advantages of low cost, good quality, conformity to the energy-saving and emission-reduction requirement and the like.
