Autoclaved aerated concrete (AAC), also known as autoclaved cellular concrete (ACC) or autoclaved lightweight concrete (ALC), was invented in the mid-1920s by the Swedish architect and inventor Johan Axel Eriksson It is a lightweight, precast building material that simultaneously provides structure, insulation, fire resistance, Construction Economy and Speed; AAC products include blocks, wall panels, floor and roof panels, and lintels
It has been refined into a highly thermally insulating concrete-based material used for both internal and external construction. Besides AAC's insulating capability, one of its advantages in construction is its quick and easy installation, the material can be routed, sanded, and cut to size on site using standard carbon steel band saws, hand saws, and drills. Even though regular cement mortar can be used, 98% of the buildings erected with AAC materials use thin bed mortar, which comes to deployment in a thickness of 3 mm. This varies according to national building codes and creates solid and compact building members. AAC material can be coated with a stucco compound or cement plaster OR POP. Materials. Siding materials such as brick or vinyl siding can also be used to cover the outside of AAC materials |

• AAC has been produced for more than 70 years, and it offers advantages over other cementations construction materials, one of the most important  being i    ts lower environmental impact.Â
• AAC’s improved thermal efficiency reduces the heating and cooling load in Buildings • AAC’s workability allows accurate cutting, which minimizes the generation of solid waste during use. • AAC’s resource efficiency gives it lower environmental impact in all phases of its life cycle, from processing of raw materials to the disposal of AAC waste. • AAC’s light weight also saves cost & energy in transportation. • AAC’s light weight saves labors. • Reduces the structural weight achieving great economy in RCC work • Low Construction Cost, with high speed output. Main ingredients include fly ash, water, quicklime, cement, aluminum powder and gypsum. The block hardness is being achieved by cement strength, and instant curing mechanism by autoclaving. Gypsum acts as a long term strength gainer. The chemical reaction due to the aluminum paste provides AAC its distinct porous structure, lightness, and insulation properties, completely different compared to other lightweight concrete materials. The finished product is a 2.5 times lighter Block compared to conventional Bricks, while providing the similar strengths. The specific gravity stays around 0.6 to 0.65. This is one single most USP of the AAC blocks, because by using these blocks in structural buildings, the builder saves around 30 to 35 % of structural steel, and concrete, as these blocks reduce the dead load on the building significantly. Assumption The major raw material Fly-Ash, an indispensable by-product of Thermal Power Plants, is an environmental threat across the globe. Power plants are facing an ever increasing challenge disposal of this polluting agent. This unit is proposed to manufacture AAC Bricks & Blocks by consuming the Fly-Ash as one of the prime raw material. Secondly, it also helps environment by saving the invaluable top soil by not using them in brick making like conventional brick making. Thirdly, they need no burning, thus further enhancing their Eco-Friendly Brand. The steam curing requires far less fuel, compared to the backing for each cubic meter of Bricks. This is the reason these bricks are also referred as Eco Bricks or popularly Green Bricks, Carbon Credit estimates are for reference purpose. The Project owner must handle his part of CDM project to get Carbon credits, through independent consultants. Carbon credit can be transacted on registration. The PCN preparation & presentation, the PDD preparation & presentation, host country approval and the UNFCCC Registration might take somewhat 6 months to 2 years year. So it may be wise to start early.
Sale price at site is estimated a conservative Rs 3200/- per cubic meter. AAC Blocks of all sizes will be manufactured according to the market requirement, though mainly stipulated sizes as per the BIS standards. Production is estimated at 80% capacity, 300 working days is considered in a year during the first year.
