What is Autoclaved Aerated Concrete (AAC)?
Autoclaved Aerated Concrete (AAC) is a lightweight, precast building material known for its thermal insulation, fire resistance, and structural efficiency in modern construction.

Understanding AAC Technology
Autoclaved Aerated Concrete (AAC) is produced using cement, lime, sand, water, and a small amount of aluminum powder. During the manufacturing process, a controlled chemical reaction generates millions of microscopic air pores within the material.
This air-entrained structure significantly reduces density while maintaining structural performance, making AAC both lightweight and durable.
After expansion, the material is precision-cut and cured under high-pressure steam inside an autoclave. This process enhances dimensional stability, compressive strength, and long-term performance.

How Autoclaved Aerated Concrete is Manufactured
Raw Material Preparation
Cement, lime, sand, and water are accurately proportioned and mixed to create a homogeneous slurry.
Expansion & Pre-Curing
A small amount of aluminum powder reacts within the mixture, generating microscopic air pores and causing the material to expand.
Cutting & Profiling
The semi-hardened material is precisely cut into blocks or panels according to required dimensions and tolerances.
High-Pressure Autoclaving
The blocks are cured under high-pressure steam in autoclaves, enhancing strength, stability, and long-term durability.
