MAPEAIR AE 20

Water-reducing admixture for concrete with mild retarding effect

Air entraining admixture for concrete resistant to freeze/thaw cycles

The main technological characteristics of cementitious mixes with aerating agents are as follows:

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.

Mapeair AE 20 may be used to great advantage if used in the following applications:

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.
