Autoclaved Aerated Concrete and it`s advantages
What is Autoclaved Aerated Concrete ?
Autoclaved Aerated Concrete, also known as AAC or aircrete, is a green precast building material present in the global market for over 70 years and is extensively used in residential, commercial and industrial construction.
AAC is a well-established building material, which has rapidly gained worldwide market share from conventional building materials because of its superior characteristics.
This eco-friendly building material is made from natural raw materials such as sand (or fly-ash), cement, lime, gypsum, aluminium powder and water. This mix creates an aerated concrete providing insulation, structure and fire protection in one lightweight product.
Thanks to the air pores in the material, AAC is a great sound and thermal insulator. The thermal conductivity (λ) values are between 0,08 – 0,16 W/(mK) depending on density used.
AAC product densities vary between 300-800 kg/m³ and compressive strength is in the range 2,5 – 6 N/mm², making it extremely resource efficient material.
AAC panels offer new possibilities for product applications beyond AAC blocks. In panel based systems, installation of prefabricated elements is fast and easy. As a result, the total cost of an installed m2 is reduced compared to traditional building methods.
The SUPER SMOOTH surface of the panels adds to quick finish as the walls are ready for direct painting.
The large size of elements also allows for faster building and reduction of installation materials and labor. For example, one standard partition panel (60cm x 300cm) is 1,8m2of wall, equivalent to 12 standard AAC blocks (25cm x 60cm). An industrial panel can even have a surface of 6m2 per element (800cm x 75cm).
All AAC products are well-suited to withstand fires, earthquakes, and other natural disasters.
AAC achieves the highest possible level of fire safety and can withstand up to 4 hours of direct fire exposure. It is non-combustible and classified as Euroclass A1.
The lightweight, load-bearing structure and high compressive strength of AAC also contributes to be the perfect building material in earthquake and hurricane prone regions.
