Air-Minus

Category: Air Entrainers and Detrainers

USE

Specialty admixture to reduce the amount of air entrained in concrete and cement based materials. Recommended for high strength grouts, high-density concrete and high strength concrete. To reduce the air entrained and entrapped in statuary and small precast pieces. To allow reduction of air in grouts mixed with high shear rates or in self-leveling materials.

ADVANTAGES

  • Reduces the amount of concrete rejected due to high entrained air content.
  • Increases unit weight of concrete.
  • Recommended for the production of heavyweight concrete.
  • Allows high speed mixing of cement and fly ash without foaming.
  • May increase compressive strength of concrete.
  • Counteracts entrained air caused by the new generation of superplasticizers.
  • Maintains slurry densities.
  • Air-Minus is available in bulk or in a patented water-soluble Fritz-Pak inner bag for convenient use at the plant or job site.

DESCRIPTION

Fritz-Pak Air-Minus is a dry powdered defoamer for use in dry blended materials, or for wet/plastic concrete. It decreases foaming and minimizes air entrainment in cement slurries, grouts, concrete and mortars. It can also be used to counteract the air entrainment caused by water reducers and plasticizers.

COMPATIBILITY

Air-Minus is compatible with most admixtures. Adding salt, surfactants, superplasticizers, air entrainers or latex to the mix can cause increased foaming or reduce the effectiveness of Air-Minus. When used with other admixtures, each admixture must be dispensed separately into the mix.
