Advantages:

ConAir®-VR introduces millions of uniformly sized and spaced air voids throughout the concrete mixture. Concrete containing these tiny air bubbles has been proven far more resistant to freezing and thawing than plain concrete.

ConAir®-VR in hardened concrete reduces permeability and enhances the resistance to surface deterioration caused by de-icing chemicals. Concrete containing ConAir®-VR requires less water; therefore, bleeding is reduced. Entrained air bubbles act as “ball-bearings” to greatly improve the plasticity and workability of the concrete, making it easier to flow into forms or be pumped into place.

Concrete mixes designed using ConAir®-VR result in a reduction of segregation and honeycombing with smoother and more even finished surfaces.
