Detailed Process – How AAC blocks Are Manufactured
The first step in the manufacturing process of AAC blocks is the preparation of the raw materials. The materials used in the process are cement, lime, fly ash, gypsum, water, and a small amount of aluminium powder. The raw materials are mixed in the right proportions using a mixing machine.
Our fully automated batching plant enables accurate dosing, weighing and mixing of all the raw materials. The next step is mixing the prepared raw materials. The mixture is placed in a large vessel and mixed thoroughly until it forms a homogeneous mixture.
Once the mixture is prepared, it is poured into moulds and allowed to be set for a few hours. During this time, the aluminium powder reacts with the other materials in the mixture, producing hydrogen gas. This process is called aeration and results in tiny air pockets throughout the material, making it lightweight and porous.
After the blocks are poured into moulds, they are left to cure for a few hours. Once the blocks have hardened, they are removed from the moulds and cut with wires into blocks with precision accuracy. Then the blocks are placed into an Autoclave.
The blocks are then subjected to steam and heat in an autoclave. The autoclave is a high-pressure chamber that exposes the blocks to high temperatures (approx 180-190 °C) and steam, which helps to further harden and strengthen them. The autoclaving process takes several hours and is critical in ensuring that the blocks are durable and resistant to damage.
Once the blocks are removed from the autoclave, they are ready for use in construction. Each block is sorted for any damages and breaks and then packed perfectly for delivery. They can be easily cut, drilled, and shaped using standard tools, making them versatile and easy to work with.
