Company Description
Austin AAC Block is a lightweight material produced by mixing silica rich material (sand or flyash), cement, lime, gypsum, aluminium powder and water. Aluminum powder reacts chemically with cement and lime to generate hydrogen gas, this gas escapes into the air towards the end of the procedure. It is this chemical reaction that lends AAC blocks their distinct honeycomb structure, lightness, and other insulation properties.
Having undergone necessary molding and mixing, these are further cured in an autoclave (subject to high heat and pressure) that imparts them the desired strength and durability.
AAC was perfected 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. The process was patented in 1924. In 1929, the first autoclaved aerated concrete was produced in the Swedish town of Yxhult. “Yxhults Anghärdade Gasbetong”, gave birth a little later to one of the world’s trademarks for building materials, AAC Blocks, which went on to change the construction industry for good.
