The Autoclaved Aerated Concrete (AAC) was perfected in the mid-1920s by the Swedish architect and inventor Dr. Johan Eriksson. The AAC is a lightweight, non-baked material produced from the common raw materials lime, sand, cement and water, and a small amount of expansion agent. After mixing and casting, it is then cured under heat and pressure to create its unique properties.
Today, AAC has become one of the most used building materials in the world. In many countries, AAC blocks account for over 70% of the total wall materials used in the construction industry.
In Vietnam, the application of AAC blocks in civil and industrial construction works has been increasingly popular in recent years and encouraged by the Government through the issuance of any relevant regulations and circulars.
