​SikaControl®-71 AER (formerly known as MasterAir® 71) is an air entraining admixture for concrete to produce frost resistant concrete

Formerly Mischoel LP 71

What is and where to use MasterAir 71?

MasterAir 71 is an air-entraining admixture, which creates ultra-stable air bubbles that are strong, small and closely spaced. Those bubbles ensure that the concrete is able to withstand possible damages caused by frequent freezing-thawing.

How you will enjoy the benefits of MasterAir 71?

• Increased resistance to damage from freeze-thaw cycles and to scaling from de-icing salts;
• Reduced permeability - increased water tightness;
• Reduced segregation and bleeding;
• Improved plasticity and workability;
• Greatly improved stability of air entrainment;
• Improved air-void system in hardened concrete;
