- Enter the desired air voids percentage.
- Click ‘Calculate’.
Formula & Methodology
The formula used in this calculator is based on the ASTM C231 standard:
Air Voids (m³) = Total Volume (m³) * (Air Voids (%) / 100)
Real-World Examples
Data & Statistics
| Exposure Condition | Recommended Air Voids (%) |
|---|---|
| Normal exposure | 5-8 |
| Severe exposure | 10-15 |
Expert Tips
- Higher air voids content improves concrete’s resistance to freezing and thawing.
- However, excessive air voids can negatively impact concrete’s strength and durability.
