FAQ
1. What is the AAC and what product can be produced?
AAC stands for Autoclaved Aerated Concrete, which is a lightweight and durable building material made from cement, lime, sand, water, and a small amount of aluminum powder. It is produced by mixing these ingredients together, pouring the mixture into molds, allowing it to rise and expand due to reactions between the ingredients, and then curing it in an autoclave to create a strong, porous material with excellent insulation properties. AAC can be used to produce various products such as blocks, panels, floor and roof slabs, lintels, and precast reinforced elements for use in both residential and commercial construction.
2. Is AAC a new building material?
No, AAC (Autoclaved Aerated Concrete) is not a new building material. It was first invented in Sweden in the 1920s and has been used extensively in Europe, Asia, and other parts of the world for many decades. However, it has gained popularity in recent years due to its excellent insulation properties, fire resistance, durability, and sustainability, which make it an attractive alternative to traditional building materials such as concrete, brick, and wood.
- Where has AAC been used?
- Residential buildings - as a construction material for walls, floors, and roofs
- Commercial buildings - as a structural material for offices, hotels, schools, hospitals, and other public buildings
- Industrial buildings - as a material for factories, warehouses, and other industrial facilities
- Infrastructure projects - as a material for bridges, culverts, tunnels, and retaining walls
- Greenhouses - as a material for walls, roofs, and partitions
- Renovation and retrofitting projects - as a material for replacing old or damaged walls or insulation.
AAC is a versatile building material that can be used in a wide range of applications due to its excellent properties such as low density, high strength, thermal insulation, fire resistance, and sound insulation.
