Air Entrainers is a special surfactant for concrete. After mixing into concrete, it forms numerous evenly distributed stable micro air bubbles, which usually account for 4% to 7% of the concrete volume. These tiny voids act as buffer chambers to accommodate water expansion during freezing, greatly boosting concrete freeze-thaw resistance and overall durability.

Besides durability improvement, our Air-Entraining Admixture optimizes concrete workability, reduces bleeding and segregation, and fits well with other admixtures. Widely used in roads, bridges, municipal and cold-region projects. We supply liquid and powder types with stable performance, support bulk packaging and OEM service for global concrete factories.
