Autoclaved Lightweight/Aerated Concrete block,is shorted for AAC/ ALC block, using silica sand,cement and lime as the raw material,aluminium power as the foaming agent,after high temprature,high pressure steam raised.Easy to cut and install,is widely used to construct internal and external wall. ALC block is also one kind of self-heat preservation materials,makes the external wall an excellent thermal insulation system.

FAQ
1. What is Autoclaved Aerated Concrete?
Autoclaved Aerated Concrete (AAC) is a lightweight concrete that is formed into blocks and panels for a wide range of loadbearing and non-loadbearing construction applications. It is manufactured from silica sand, cement, recycled material, lime, gypsum, aluminium paste and aerating agents. It is moulded, cut and steam pressure cured in an autoclave before being packed, ready for transport.
2. Is Autoclaved Aerated Concrete a new building material?
Aerated Concrete Autoclaved (AAC) is an amazingly innovative building material that has been used in Europe for more than 80 years and in the US for more than 15 years.
3.What are the benefits of Autoclaved Aerated Concrete over other building materials?
a.Cost effective - lightweight panels allow for reduced structural components and smaller lifting equipment.
b. Excellent thermal resistance performance.
c.Acoustic performance - effective sound transmission barrier between external and internal environments of the building.
d.Excellent fire rating properties.
e.No wet trades - less mess and a cleaner, safer work area.
f.Less wastage - significantly reduced waste as panels can be custom-made to length requirements.
g. Fewer waste bins and less crane movements.
h. Design flexibility - panels can be easily cut and routed to suit design requirements.
i. Panel lengths up to 6 metres.
j. Strong, secure and durable with corrosion protected steel-reinforced panels.
