Coal ash autoclaved brick containing construction garbage

2013 
The invention discloses a coal ash autoclaved brick containing construction garbage, wherein the coal ash autoclaved brick is prepared from the following materials in parts by weight: 30-35 parts of coal ash, 20-25 parts of lime, 45-50 parts of the construction garbage and 2-4 parts of composite nanometer powder. The composite nanometer powder can remarkably increase the rupture strength of the coal ash autoclaved brick, and a small amount of latex powder can also increase the rupture strength of the coal ash autoclaved brick. Therefore, the coal ash autoclaved brick is uniform in mixing, is not likely to shrink and crack, and is long in service life. Meanwhile, the coal ash autoclaved brick utilizes waste residues like construction garbage; thus the waste is turned into wealth, and economization and environmental protection are achieved.
