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.
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.
