Autoclaved Aerated Concrete roots go back to the 1920’s, when Sweden was enduring an extreme shortage of wood due to deforestation. Desperately in need of an alternative building material, John Axel Eriksson developed the first Autoclave Aerated Concrete (AAC).
Later on about 45 years ago in West Germany, Josef Hebel a building contractor developed a more cost-effective building system by utilising mixers, moulds and cutting system and incorporated steel into the production for better strength. Architects and builders quickly saw the advantages of this strong yet lightweight material and were soon utilising its range of properties in all types of construction.
The demand for Autoclaved Aerated Concrete systems were so great that till 1995 there were 51 plant around the world with production capacity of 31 million m3 per year, which by 1998 has increased to 150 plant and capacity of 50 million m3 per year.
