WHAT IS AAC (Autoclaved Aerated Concrete)
Autoclaved Aerated Concrete (AAC), also known as aircrete or AAC, is a precast building material that has been a staple in the global market for over 70 years. Its usage in residential, commercial and industrial construction is widespread and it is recognized as an eco-friendly building material.
AAC has become a popular alternative to traditional building materials due to its superior properties which has enabled it to gain worldwide market share.
This lightweight product is made from natural raw materials including sand (or fly-ash), cement, lime, gypsum, aluminium powder and water. The resulting aerated concrete provides insulation, structure and fire protection in a single product.
Energy and Resource Efficiency
Thanks to the air pores within the material, AAC serves as an excellent sound and thermal insulator. Depending on the density used, its thermal conductivity values typically range from 0.08 to 0.16 W/(mK). Additionally, AAC products come in varying densities between 300-800 kg/m³, and boast compressive strength between 2.5-6 N/mm², making it an incredibly efficient resource.
Fast and Easy Building System
AAC panels offer a range of product applications, beyond traditional AAC blocks. With panel-based systems, the installation of pre-fabricated elements is quick and straightforward, resulting in a reduction in the total cost of an installed m2 when compared to conventional building methods. The SUPER SMOOTH surface of the panels also means that walls are ready for direct painting, simplifying the finishing process.
Large Format Efficiency
The use of larger building elements offers advantages such as faster construction and reduced installation materials and labor. For instance, a single standard partition panel (60cm x 300cm) can cover 1.8m2 of wall, which is the equivalent of 12 standard AAC blocks (25cm x 60cm). Industrial panels can go even further, with each element having a surface area of up to 6m2 (800cm x 75cm).
Fire & Natural Disaster Resistance
AAC is a durable and robust building material capable of withstanding natural disasters such as fires, earthquakes, and hurricanes. With the highest level of fire safety attainable, AAC can endure up to four hours of direct fire exposure and is classified as Euroclass A1. Furthermore, due to its lightweight, load-bearing structure, and high compressive strength, AAC is an ideal building material in regions prone to earthquakes and hurricanes.
