Autoclaved Aerated Concrete (AAC PLANT) Technology
Autoclaved Aerated Concrete (AAC) block and panel have become the main building materials in construction industry. AAC technology has developed over 90 years, and China has introduced this technology before 40 years, our company is the earliest manufacture and R&D producer of Aerated Concrete (AAC) machinery, and our technology has reached the advanced level of Aerated Concrete (AAC) machine industry. The sales volume and comprehensive indexes of our Aerated Concrete (AAC) equipment are ahead of others in China. Aerated concrete (i.e. aeroconcrete, earblock) is the perfect wall material to replace the traditional solid clay brick.
The advantages of autoclaved aerated concrete (AAC)
There are advantages of autoclaved aerated concrete(AAC):
- Perfect heat storage capacity helps to avoid high temperatures in summer and heat losses in winter,
- AAC can regulate humidity and prevent from fungus and mustiness inside the house,
- Water vapors permeability is 0,25 - 0,22Ng (compare with wood - 0,15Ng, brick - 0,05 - 0,1Ng),
- High frost-resistance,
- Due to low density wall made of aerated concrete is light as 3 times as solid clay brick,
- Aerated concrete is easy to cut, install and transport,
- Man-hours needed for installation of aerated concrete blocks are three times less than for brick walls.
