- Form
- Liquid (powder on request)
- Recommended dosage
- 0.01%–0.05% of cementitious material
Overview
A rosin AEA that introduces abundant fine, uniform, stable air voids via surface activity, a classic component of freeze-thaw resistant concrete.
Key benefits
- Stable voids with low spacing factor
- Markedly better freeze-thaw durability
- Improves workability and pumpability
