Overview:
Steam Block, also known as Autoclaved Aerated Concrete (AAC), is a lightweight, high-performance building material made from sand, lime, cement, and aluminum powder. It undergoes a steam curing process in an autoclave, resulting in a porous structure that provides excellent insulation, strength, and fire resistance.
Why You Should Use It:
- Lightweight: Reduces the structural load on buildings.
- Thermal Insulation: Minimizes heat transfer, reducing energy costs.
- Fire Resistance: Non-combustible and withstands high temperatures.
- Soundproofing: Effective in reducing noise levels.
- Eco-Friendly: Manufactured using natural raw materials and is recyclable.
- Easy Handling: Can be cut and shaped with simple tools.

- Commercial Buildings: Integrated into office buildings for fireproof and soundproof walls.
- Prefabricated Constructions: Utilized in modular homes for quick assembly and durability.
Applications in Practice:
Steam Blocks are a preferred choice in modern construction for their insulation and structural benefits. Their fire-resistant nature makes them ideal for high-rise buildings, and their lightweight properties simplify transportation and installation, reducing labor costs.
Installation Recommendations:
- Cutting: Use standard saws for precise cutting.
- Adhesion: Requires specialized thin-bed mortar for bonding.
- Finishing: Can be plastered or painted for aesthetic purposes.
