About AAC BLOCKS
Autoclaved Aerated Concrete (AAC) is a certified green building material, which can be used for commercial, industrial and residential construction. It is porous, non-toxic, reusable, renewable and recyclable.It is a technology developed in the mid-1920s by the Swedish architect and inventor Dr. Johan Axel Eriksson, working with Professor Henrik Kreüger at the Royal Institute of Technology.
AAC forms through a process of aeration of a mix of various materials which includes silica (through fly-ash/sand), quicklime, cement, gypsum and aluminium powder. The aerated mix is processed through autoclaving which entails highly pressurised curing of aerated materials, giving it a cellular shape. AAC can be used in various forms such as blocks, wall/floor/roof panels and lintels.
AAC blocks are used as a substitute for the conventional building masonry and have been widely accepted globally because of its beneficial properties such as being light weight, thermal & sound insulation properties, fire resistance, termite resistance, earthquake resistance and several other benefits which ease the process of construction while providing long term benefits to the end users. It is also an environment friendly product as its processing hardly causes pollution and also boasts the consumption of fly ash which is a waste material of thermal power plants.
