What is Aerated aluminum powder?

Aerated aluminum powder is a powder-like material made from aluminum powder and additives. It is an important raw material for aerated concrete, which is a lightweight, high-strength building material with good thermal insulation and soundproofing properties.

Aerated aluminum powder


In the production of aerated concrete, it reacts with lime and water to produce hydrogen gas, which forms a porous structure in the concrete. Aerated aluminum powder is an important raw material for aerated concrete and has the following characteristics:

      • Large gas production, short gas production time, and stable gas production can be adjusted according to different process requirements.
      • Easy to disperse and mix evenly with cement slurry, and not easy to stratify.
      • Low cost and easy to use.

The use of aerated aluminum powder can give aerated concrete the following advantages:

      • Light weight and high strength, with a self-weight reduction of more than 40% compared to ordinary brick-concrete structures.
      • Good thermal insulation performance, with a thermal conductivity coefficient of 0.11-0.16 W/mK, which is 1/4-1/5 of that of clay bricks.
      • Good sound insulation effect, with a wall thickness of 10 mm reaching 41 decibels.
      • Strong seismic resistance, with a light capacity, good overall performance, and small inertia during an earthquake.
      • Aerated aluminum powder is widely used in the production of aerated concrete blocks, panels, and pipes, and is an important component of building materials.

Specific applications of aerated aluminum powder:

      • Aerated concrete blocks: The main application area of aerated aluminum powder, is used for the construction of walls and partitions.
      • Aerated concrete panels: Used for interior and exterior walls, ceilings, and partitions.
      • Aerated concrete pipes: Used for pipes and culverts.

The use of aerated aluminum powder provides new ideas for the development of building materials and is of great significance in terms of energy conservation and environmental protection, and improving building performance.
