Welcome to Liteweight AAC Block

Manufacture and thus supply the best quality sustainable green construction products and thus lead to value creation that eventually lays foundation for a continually prospering establishment with clients and suppliers.


The Autoclaved Aerated Concrete (AAC) material was developed in 1924 in Sweden. It has become one of the most used building materials in Europe and is rapidly growsing in many other countries around the world. AAC is produced from the common materials lime, sand, cement and water, and a small amount of rising agent. After mixing and molding, it is then autoclaved under heat and pressure to create its unique properties. AAC has excellent thermal insulation and acoustic absorption properties. AAC is fire and pest resistant, and is economically and environmentally superior to the more traditional structural building materials such as concrete, wood, brick and stone. At the point when AAC is blended and cast in structures, a few compound responses occur that give AAC its light weight (20% of the heaviness of cement) and warm properties. Aluminum powder responds with calcium hydroxide and water to frame hydrogen. The hydrogen gas froths and copies the volume of the crude blend making gas rises to 3mm (⅛ inch) in distance across. Toward the end of the frothing procedure, the hydrogen escapes into the air and is supplanted via air. AAC Blocks is a unique and excellent type of building material due to its super heat, fire and sound resistance, AAC blocks are lightweight and offers ultimate workability, flexibility and durability. Its main ingredients include sand, water, quicklime, cement and gypsum. 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. When the forms are removed from the material, it is solid but still soft. It is then cut into either blocks or panels, and placed in an autoclave chamber for 12 hours. During this steam pressure hardening process, when the temperature reaches 190° Celsius (374° Fahrenheit) and the pressure reaches 8 to 12 bars, quartz sand reacts with calcium hydroxide to form calcium silicate hydrate, which gives AAC its high strength and other unique properties. Because of the relatively low temperature used AAC blocks are not considered fired brick but a lightweight concrete masonry unit. After the autoclaving process, the material is ready for immediate use on the construction site. Depending on its density, up to 80% of the volume of an AAC block is air. AAC's low density also accounts for its low structural compression strength. It can carry loads of up to 8 MPa (1,160 PSI), approximately 50% of the compressive strength of regular concrete. AAC offers incredible opportunities to increase building quality and at the same time reduce costs at the construction site. AAC is produced out of a mix of quartz sand and/or pulverized fly ash (PFA), lime, cement, gypsum, water and aluminum and is hardened by steam-curing in autoclaves. As a result of its excellent properties, AAC is used in many building constructions, for example in residential homes, commercial and industrial buildings, schools, hospitals, hotels and many other applications. AAC contains 60% to 85% air by volume.

Our Mission

Revolutionise the Indian construction industry by introducing the latest AAC block building technique. Establish Balaji Industries as a company that delivers utmost quality and keeps up the commitment of creating structures that surpass the highest quality standards. To present a company that based upon the culture of responsiveness and commitment, create worth for the stakeholders. Foster a learning environment that consistently educates all employees and thus assists Balaji Industries with its objective of continuous progression.

Our Mission

Fast Installation

Liteweight AAC Blocks are easy to work with common tools making construction onsite fastern than ever.

There are a full range of tools that are specially designed to assist the block layer in installing AAC masonry products and increase productivity at the job site.


Liteweight AAC Blocks are manufactured from fly ash 60% (waste from thermal power,called "Pollutant fly ash")

which save lot of soil (of fertilise land) require to manufacture bricks.

Ribbed Face

Liteweight AAC Blocks comes with a ribbed finish on face. It helps in better bonding of plaster with the blocks.

Liteweight is the only block with ribbed finish in the industry.
