Abstract

The invention provides an autoclaved flyash-lime brick and a manufacturing method of the autoclaved flyash-lime brick, and refers to the technical field of building materials. The autoclaved flyash-lime brick comprises the following raw materials, coal gasification slag, fly ash, aggregate, acetylene sludge, and ardealite; according to a formula of the invention, content of fly ash is low; meanwhile, a certain amount of coal gasification slag is mixed, thus the production environment of big dust capacity caused by high content of fly ash is improved, utilization of coal gasification slag is increased, production cost is reduced, and performance index of the autoclaved flyash-lime brick product is improved; moreover, the product appearance and color are similar to antique black brick.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an autoclaved fly ash brick and a manufacturing method thereof. Background technique [0002] Autoclaved fly ash brick is a new wall material, which is widely used in the interior and exterior walls of various civil buildings, public buildings and industrial plants, as well as the foundation of houses. Autoclaved fly ash bricks are an alternative to fired clay bricks. Fired clay bricks use clay as the main raw material, and there are solid and hollow clay bricks. The clay resources required for the production of solid clay bricks are relatively high-quality clay in arable land. The promotion of autoclaved fly ash bricks plays a positive role in reducing environmental pollution, protecting cultivated land, and improving building functions. [0003] In the prior art, autoclaved fly ash bricks are made of fly ash, lime or cement as the main raw material, mixed with appr...
