Characteristics Of Autoclaved Aerated Concrete

 Autoclaved Aerated Concrete is a widely popular building material recently being used in the modern structures. It is a lightweight precast, foam concrete that is used for multiple benefits such providing structure, strength, insulation, fire and mold resistance. A good fact about this material is its monopoly over other building material for it can be used as interior as well as exterior wall options.

Aerated Autoclaved Concrete is made up of a careful composition of  Quartz sand, calcined gypsum, lime (mineral) and/or cement and water along with little quantity of aluminium powder. The material is now popularly accepted in China, India, Australia and middle east.

Characteristics :


Autoclaved Aerated Concrete is known for its durable essence. Autoclaved Aerated Concrete bricks are made out of concrete cakes that are moulded in high temperatures. When cool, the material has high tensile strength and an effective replacement for brick and mortar walls.


Due to its high insulating capacity, the material is widely used in external and internal walls of buildings. This make it fireproof and the best way to ensure safety.

Thermal Efficiency

Autoclaved Aerated Concrete comes with inherent character of remarkable thermal efficiency. Along with it being concrete based, it is prefered over others as a better solution to two fold problem of building walls and its thermal insulation.

Physical Attributes

A conventional brick is handy and used in high quantity (in numbers). Autoclaved Aerated Concrete bricks on the other side are large resulting in less joints and faster masonry work. This gives it another advantage over conventional methods.


The material is durable and tough, but at the same time, it tends to be lightweight as much as th of normal concrete. This gives the workforce ability to easily handle the material and savings in time involved in construction.


Pores can be seen when material is deeply observed. This maintains ventilation in the room. It is effective to absorb moisture and release humidity.
