CHRYSO®Air G500 is an air entraining agent creating stable microscopic air bubbles in concrete and mortar.

CHRYSO®Air G500 protects the concrete effectively against frost/defrost cycles and the action of defrosting salts.


CHRYSO®Air G500 creates a matrix of stable, evenly distributed air bubbles in both the fresh and hydrated system employed.

In fresh concrete, CHRYSO®Air G500 also has a plasticising effect. It limits the amount of segregation and reduces or even eliminates bleeding.

Using CHRYSO®Air G500 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.

CHRYSO®Air G500 improve workability - the micro air bubbles entrained act as ball bearings, lubricating the mix.

Domains of application

CHRYSO®Air G500 is recommended for all concrete and mortar mixes where low density and entrained air is required.

  1. All types of cement
  2. Highway slabs, runways
  3. Dams, reservoirs
  4. Road & maritime construction
  5. Compensation of the harshness of some natural sands with low fine particle content
  6. Concrete exposed to thaw
  7. Extruded concrete
