CHRYSO®Air R² is an air entraining agent creating stable microscopic air bubbles in concrete and mortar.
CHRYSO®Air R² protects the concrete effectively against frost/defrost cycles and the action of defrosting salts due to the spreading of particularly small size of air bubbles entrained and stabilized.
CHRYSO®Air R² creates a matrix of stable, evenly distributed air bubbles in both the fresh and hydrated concrete.
In fresh concrete, CHRYSO®Air R² has a plasticising and water reduction effect at constant workability. The air bubbles act as fine particles, and augment the workability of the concrete.
Using CHRYSO®Air R² prevents many compatibility problems between cement/sand/admixtures.
Its highly effective action ensures its compatibility with all types if superplasticizers, and especially with CHRYSO®Optima and CHRYSO®Premia ranges.
Moreover, adding CHRYSO®Air R² helps to trap water. Therefore, it limits segregation and reduces, even prevents, from bleeding.
CHRYSO®Air R² is recommended for all concrete and mortar mixes where low density and entrained air is required.
