Aluminium powders and pastes for AAC block

  Product Description:   Aluminum paste is often used in the production of Aerated Autoclaved Concrete (AAC) blocks as a foaming agent. Its primary function is to create air bubbles within the concrete mixture, which reduces its density and increases its porosity. This results in a lightweight, yet strong and durable building material. The process typically involves mixing the aluminum paste with water and cement slurry. The aluminum paste reacts with the water to produce hydrogen gas, which gets trapped in the slurry, forming the air bubbles. The resulting mixture is then poured into molds to form the AAC blocks. Here's a simplified overview of the process: 1. **Mixing**: Combine the cement, sand, and other aggregate materials. 2. **Adding Aluminum Paste**: Add the aluminum paste to the mix along with water. 3. **Reaction**: The aluminum paste reacts with the water to produce hydrogen gas, which gets incorporated into the mix. 4. **Casting**: Pour the mixed slurry into th…
