Autoclaved Aerated Concrete (AAC) blocks were developed in the 1920s to resolve the mounting pressure on forestry resources for construction purposes in the post First World War Europe. Gaining popularity globally for the last several decades, today the technology has scaled up to address the complex infrastructural challenges of the 21st century.
It is formed as a reaction of aluminum metal with a blending proportion of lime, cement, gypsum & fly ash. The hydrogen gas escaping from the reaction gives it a strong honey-comb structure. It is further cured in an autoclave under high-pressure steam to give its desired strength.
Its Lightweight reduces the dead-weight of the structure drastically. Studies show a reduction in foundation steel by 15% and cement by 10% if AAC Blocks are used.
Best in class thermal insulation results in significant savings in HVAC cost.
