Embodiment 1

[0041] The autoclaved fly ash brick of this embodiment includes the following raw materials in weight percentages: coal gasifier slag 5%, fly ash 15%, aggregate 50%, calcium carbide slag 20%, and phosphogypsum 10%.

[0042] According to the weight percentage of raw materials in this embodiment, the manufacturing method of autoclaved fly ash brick includes the following steps:

[0043] S1. Weigh each raw material according to the weight percentage of the raw material;

[0044] S2. The coal gasification furnace slag, aggregate, calcium carbide slag and phosphogypsum are uniformly measured and sent into the feeding hopper through the belt, and then the materials and fly ash in the feeding hopper are added to the mixer at the same time, and the mixing time is 3 minutes. ;

[0045] S3. Send the evenly stirred material in step S2 to the digestion chamber, store for 2 hours for digestion, then send it to the powder mixer, and then send it to the automatic hydraulic brick press for compressio...

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 inner and outer walls of various civil buildings, public buildings and industrial plants, as well as the foundation of houses. Autoclaved fly ash bricks are products that replace sintered clay bricks. Sintered clay bricks use clay as the main raw material. There are solid and hollow clay bricks. The clay resources required to produce solid clay bricks are the higher quality clays in arable land. The promotion of autoclaved fly ash bricks has a positive effect in reducing environmental pollution, protecting arable land, and improving building functions. [0003] In the prior art, autoclaved fly ash bricks are made of fly ash, lime or cement as main raw materials, mixed with appropriate amounts of gypsum and...
