RVR-15 is specially formulated for use as an air entraining admixture for concrete. RVR-15 is manufactured under strict quality control standards to insure uniform performance at the job site.

ADVANTAGES:

RVR-15 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. RVR-15 in hardened concrete reduces permeability and enhances the resistance to surface deterioration caused by de-icing chemicals. Concrete containing RVR-15 requires less water, therefore bleeding is reduced. RVR-15 aids in finishing and produces a more water tight concrete with a lower water-cement ratio. The 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 RVR-15 result in a reduction of segregation and honeycombing with smoother and more even finished surfaces.

USES:

RVR-15 may be used wherever air entrainment is required by concrete specifications. It is particularly useful in:

* All commercial and residential concrete

* Mass concrete

* High cement, low slump paving mixes

* Mixes with high carbon content fly ash

* Concrete using high-alkali cement

* All concrete to be exposed to freezing and thawing conditions

* Concrete to be mixed for an extended period of time
