Aluminum Powder for Aerated Concrete
Aluminum powder and pastes for building materials is a kind of concrete additive, which can improve the gas evolution and stability, and help to enhance the strength and durability of concrete.
Aluminum powder can react with calcium hydroxide in the water to form aluminum hydroxide. This compound can fill the micro-holes and cracks in the concrete, thus improving the compactness and durability of the concrete.
Aluminum powder can promote cement hydration reactions in concrete, improving its strength and stiffness.
In aerated concrete, aluminum powder can be used as a foaming agent. When mixed with water, it produces a lot of water vapor and forms pores, which makes the concrete lighter and better in heat insulation. The aerated concrete has a two-in-one effect on building and thermal insulation.
