AAC Blocks manufacturing process. Flow chart for Autoclaved Aerated Concrete production, i.e AAC blocks manufacturing process: Fly ash or sand: Fly ash is mixed with water to form fly ash we got 44 bricks per cubic meter so for each block it costs around 3050/44=69.32 ( approximately 70/ )Fly ash bricks vs AAC blocks Features, Preparation, and ,Fly ash bricks vs AAC blocks. Parameters. FLY ASH BRICKS. AAC BLOCKS. Major component. Fly ash bricks use the fly ash as major raw material. In Acc blocks,aluminum acts as major component factor. Percentage composition. Fly ash 50%80% Sand 20%40% Cement 5%30% Gypsm 2% 5%.Fly ash Bricks: Properties, Advantages & Disadvantages,The production of clay brick damages the topsoil and prevents fly ash in the process of manufacturing bricks, there is no solid loss. Flyash bricks are stronger, more uniform, and denser than clay bricks. Their mortar consumption is low, their dissipation is only 1% against clay bricks which is around 10%. Disadvantages of Fly ash Bricks:
Manufacturing of Fly ash bricks process is done by using a manually operated machine. The following points were followed in the manufacturing of compacted fly ash bricks (1) Fly ash and sand (fly ash bricks mixing ratio is 0.35 fly ash and 0.65 sand, by weight) were mixed in a dry state. Required quantities of lime and gypsum were added to Fly Ash LimeBricks Civil Solution,The manufacturing process of fly ash bricks is semiautomatic of fully automatic with state of the art technology.

As part of the literature review, the use of autoclaved aerated concrete and brick wastes has been evaluated. Autoclaved concrete has been chosen because it is a typical lowstrength, cementbased construction material and demolition waste that is currently disposed of in landfills, making it quite a challenge for direct use as a supplementaryHongfa Automatic AAC ALC Autoclaved Aerated Concrete ,Unlike brick manufacturing process which uses previous top layer agricultural soil, AAC uses Fly Ash (65% of its weight), thus provides the most constructive solution to the nation’s fly ash utilization problem.
