The use of Autoclaved Aerated Concrete Blocks is continuously growing for many reasons like compatibility, ease in use, convenience, safety, and superior quality. Aerobild’s AAC Blocks are the perfect replacement for conventional clay bricks. We manufacture our AAC blocks in one of the largest and advanced manufacturing units in India. Keen to the smallest detail, advanced technology and expert workmanship made us the leaders of the industry.
Aerobild symbolizes the synergy and advancements of the construction industry from 90 years, precisely, from the invention of the AAC block in the mid-1920s by Dr. Johan Axel Eriksson. Autoclaved Aerated Concrete Blocks are considered as one of the finest and greatest inventions of the construction industry. AAC blocks are lightweight, fire-resistant, have thermal insulation and solid structure, and are easy to work with. AAC is a full-fledged solution for industrial, residential, and commercial building requirements.
Aerobild AAC blocks are nature-friendly and made with recycled materials. The main components used in the manufacturing of AAC blocks are finely powdered sand, calcined gypsum, lime, cement, aluminum powder, fly ash (which has 50-65% silica content), and the presence of water. The slurry formed upon adding the water is poured into a mold for curing to create a brick shape.
The addition of aluminum causes the expansion of the mixture in the aeration process. The reaction between aluminum and the mixture releases hydrogen gas and forms microscopic bubbles. When the hydrogen gas evaporates, it leaves bubbles filled with air, which expands the concrete to about five times its original volume in the mold.
After a few hours, the slurry firms up and is transported to a cutting machine, where it is cut precisely into blocks, panels, or lintels of specific size as required. Waste material is recycled back for crushing and remixing.
The cut aerated concrete is further cured in a pressure chamber and is exposed to high-pressure saturated steam for up to 12 hours. The chamber is called an autoclave, and the curing process is autoclaving.
Autoclaving hardens the aerated concrete blocks, panels, and lintels, rendering them airtight, lightweight, non-toxic, and non-organic and loading them with superlative advantages/benefits that make them the smartest building material. After autoclaving, the blocks are ready to be packed and delivered.
One-fourth of the raw material would suffice to the creation of the block of ideal size. About 80% of the Aerobild AAC are pores that require less raw material.
Aerobild used fly ash as the main component in manufacturing, which is an industrial wastage that redefines recycling. And manufacturing wastage can be used back in making AAC again, which is a commendable step towards eco-friendliness.
The energy consumed during the whole process of manufacturing AAC blocks is still two to three times lower than producing other building materials such as clay bricks.
Aerobild AAC blocks manufacturing releases very low amounts of gases such as CO2, CO, and NO, even during the steaming process, in comparison with the burning of clay bricks, and ensures zero influences of pollutants and toxic waste.
Aerobild AAC blocks provide thermal insulation to buildings that need supplementary thermal insulation, and buildings built with Aerobild AAC blocks require less effort to heat or cool the space.
Aerobild AAC block’s porous nature and breathable quality ensure lower moisture and consequently achieves relative humidity.
Aerobild AAC blocks are about five times lighter than conventional clay bricks and three times stronger than them.
