Autoclaved Aerated Concrete Blocks and Panels

Invented in 1920, by a Swedish scientist Mr. John Axel Ericson, Autoclaved Aerated Concrete or AAC blocks, is a steam-cured cementitous product manufactured from a mix of pulverized fly ash, cement, lime, gypsum and an aeration agent, giving it its unique cellular lightweight internal structure. Considered an intelligent building solutions system because of its light weight nature, excellent thermal insulation and acoustic properties and energy efficiency, AAC blocks is replaced to all natural external elements both biological and non-biological.

In India, this product has been manufactured since early 1970s. AAC blocks are also widely used in Europe, Middle East, South East Asia and China.

As a revolutionary precast building material, AAC blocks offer a unique combination of high durability and strength, low weight, unprecedented build ability and superior ecological green features. This state of the art green building material which is in many parts of the country fast replacing ordinary red clay bricks and fly ash bricks for its superior quality and saving potentials in the first and revenue maintenance cost of building. The blocks and panels are used for all kinds of walls, external or internal, non-load bearing walls etc. AAC blocks today is the preferred choice of material for all building applications.

UAL also manufactures thin bed mortar ideal for application for binding material for  AAC blocks.
