In the production of aerated concrete, the choice between aluminum powder and aluminum paste directly impacts bubble formation, block density, and overall AAC quality. This article will explain the differences in their performance characteristics and the correct selection approach for AAC manufacturers.
Aluminum powder and aluminum paste are both widely used in the aerated concrete industry. When reacting with lime and water, they produce hydrogen gas. This gas forms internal pores, imparting the lightweight structural characteristics to aerated concrete.
Key roles:
Responsible for controlled expansion
Influences block density
Affects mechanical strength and uniformity
Recent data from the Aluminum Pigment Market shows growing demand for AAC-grade reactive aluminum materials due to rising construction needs in Asia, the Middle East, and Europe.
Aluminium powder for AAC is a fine and highly reactive powder. It is commonly used in large-scale AAC production lines.
Fast hydrogen release
Precise reaction speed control
Widely used in traditional AAC formulations
You need strong expansion in large molds
Your factory uses dry-feed systems
You need cost-effective mass production
Aluminum paste for AAC is aluminium powder dispersed in water or solvent. This improves handling safety and provides more stable reactivity.
Lower dust emission
More stable gas release
Safer storage and transportation
You require higher precision in expansion
You want safer and cleaner dosing
Water-based formulation is preferred in your process
Below are the three differences AAC manufacturers care about most:
Aluminium powder: Higher reactivity due to dry, fine particles.
Aluminum paste: Slightly slower and more controlled reaction.
This directly affects pore size and block uniformity.
Powder: Can be dusty; requires explosion-proof material handling.
Paste: Significantly safer due to moisture content.
Powder: Activates quickly when mixed into the slurry.
Paste: Offers longer working time and smoother dispersion.
| Property | Aluminium Powder for AAC | Aluminum Paste for AAC |
|---|---|---|
| Form | Dry, fine powder | Water/solvent-based slurry |
| Safety | Higher dust risk | Low dust, safer |
| Reactivity | Fast, aggressive | Controlled, predictable |
| Cost | More economical | Slightly higher |
| Precision | Medium | High |
| Best for | High-volume production | Quality-focused AAC lines |
Use aluminium powder for AAC if:
Your plant needs strong lift/expansion
Low cost is a priority
Operators are trained to handle reactive powders
Use aluminum paste for AAC if:
You want maximum dimensional accuracy
Your system prefers wet dosing
You need safer handling in humid environments
Silver Rocket provides both reactive forms with customizable reactivity levels, optimized for different AAC production lines.
Aluminium powder produces slightly more hydrogen due to higher surface activity, but aluminum paste offers better control.
Not directly. Formulation and dosing must be adjusted based on reactivity and moisture content.
To reduce dust, improve safety, and gain more consistent pore structure.
Yes, but improved stability and reduced waste often balance the cost.
Yes. Silver Rocket offers tailored aluminium powder and aluminum paste for AAC with controlled reaction curves.
Understanding the difference between aluminium powder and aluminum paste is essential for producing high-quality AAC blocks. Powder is reactive and cost-efficient, while paste offers safety and precision. Choosing the correct material ensures better performance, stability, and production efficiency.
For optimized AAC materials, Silver Rocket Metallic Pigment Co.,Ltd. provides industry-proven aluminium powder and aluminum paste with customizable reactivity, stable supply, and factory-direct pricing.
