Abstract

The invention discloses an autoclaved brick containing incineration ash and a preparation method thereof. The autoclaved brick is prepared from, by weight, 10-20 parts of diatomite, 10-20 parts of Portland cement, 3-5 parts of white carbon black, 4-6 parts of titanium dioxide, 50-60 parts of incineration ash and 6-8 parts of water. The autoclaved brick containing incineration ash has the advantages that the incineration ash serves as a main component to manufacture the autoclaved brick, namely the discharge problem of the autoclaved brick is solved, a new source is also provided for raw materials of the autoclaved brick, and the manufacturing cost of the autoclaved brick is reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an autoclaved brick and a preparation method thereof. Background technique [0002] Using fly ash, coal cinder, coal gangue, tailings slag, chemical slag or natural sand, sea mud, etc. (one or more of the above raw materials) as the main raw materials, a new type of wall material manufactured without high-temperature calcination is called It is unburned brick. Among them, the representative one is the autoclaved brick. Autoclaved bricks have good appearance quality, high strength and light weight, and are ideal substitutes for solid clay bricks. They can be widely used in building foundations and internal and external walls, saving non-renewable clay resources, and effectively protecting cultivated land and the environment. However, the existing autoclaved bricks usually use fly ash as the main raw material, which has poor strength and durability. [0003] Chinese i...
