When designing high-density concrete mixes, one of the most challenging characteristics to maintain is air content. Unlike other concrete mixes, high-density concrete mixes require very low air content. Fritz-Pak’s Air Minus offers an easy way to control the air content at the job site. Fritz-Pak’s air-detraining admixture’s chemical structure lowers the concrete mix’s water tension. This lower tension reduces the development of air bubbles and releases the ones that have already formed. An air-dentrainer, such as Air Minus, offers a cost-effective method for reducing entrained air caused by superplasticizers or fly ash in the concrete mix. Air minus does not contain hazardous materials and comes packaged in our signature water-soluble bags for easy use.
Using an air-detraining admixture can sometimes be a little tricky. That’s why we created a troubleshooting video to help you get the results you need. Don’t forget to follow our social media channels for more information about how our admixtures can improve your concrete.

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.
