MAPEAIR AE 20

Air entraining admixture for concrete resistant to freeze/thaw cycles

Mapeair AE 20 is a surfactant admixture designed to entrain micro air bubbles in concrete exposed to freeze/thaw cycles.

Mapeair AE 20 is ideal for:

Durable concrete exposed to thermal fluctuations around freezing point
Lean concrete (cement content less than 250 kg/m³) with a low fine sand content for pumping
Concrete with lightweight aggregates to improve the homogeneity, workability and application of the mix

ADVANTAGES:

Resistance to freeze-thaw cycles
Better pumping properties for lean concrete with a low fine sand content
Lower segregation in concrete made from lightweight aggregates
