Aluminum pastes are essential additives for Aerated Autoclaved Concrete (AAC). Aluminum paste for AAC block series expands and strengthens AAC blocks, improving thermal insulation and durability.
At CI industry, aluminum paste for AAC or aluminum powder for AAC is used in concrete to produce lightweight AAC. CI Industry's aluminum paste for AAC block series offers optimal particle size distribution and reactivity, ensuring uniform air voids and high yield. With easy dispersion and precise dosage control, they reduce production costs and enhance workability. For example, AAC block adhesive manufacturers can reduce the consumption of aluminium up to 10% by using our aluminum paste for AAC block series.

Aluminum powder for AAC reacts with the alkaline environment of concrete, producing hydrogen gas. This gas creates tiny bubbles within the concrete matrix, resulting in a lighter, more insulating material - Autoclaved Aerated Concrete (AAC). Here's the outline of the process:
* Preparation of Ingredients: Gather necessary raw materials, including cement, sand, water, and aluminum paste for AAC block production. The aluminum paste reacts with the alkaline environment to produce hydrogen gas, forming tiny bubbles in the AAC matrix.
* Mixing: Thoroughly mix the ingredients to form a homogeneous slurry, ensuring the aluminum paste for AAC block is evenly distributed. This uniform distribution is crucial for consistent bubble formation, contributing to the material’s lightweight and insulating properties.
* Casting and Molding: Pour the mixed slurry into molds designed to accommodate expansion during the aeration reaction. Proper casting and molding are essential for achieving the desired dimensions and structural integrity.
* Aeration Reaction: The aluminum paste for AAC block reacts with the alkaline components, producing hydrogen gas and creating tiny bubbles. These bubbles cause the slurry to rise and fill the mold, giving AAC its unique properties.
* Curing: Allow the blocks to cure, harden and gaining strength. This process can be accelerated in an autoclave, enhancing the strength and durability of the AAC blocks.
* Finishing and Quality Control: Once cured, remove the AAC blocks from the molds and finish them to achieve the desired texture and dimensions. Implement quality control measures to ensure each block meets standards. AAC block adhesive is used during construction to bond the blocks, providing strong and durable joints that enhance structural stability.
The air pockets generated during production are the secret behind aerated concrete's remarkable properties.
* Lightweight
* Excellent Insulation
* Fire Resistance
