<br /> DESCRIPTION:
<br /> COMPATIBILITY WITH OTHER ADMIXTURES:
<br /> PolorSet® is a non-corrosive, non-chloride admixture for PolarSet is compatible with air-entraining admixtures such
<br /> concrete. It accelerates cement hydration resulting in as DAREX Ile', DARAVAIRt' and AIRALON-20 AEAe; water
<br /> shortened setting times and increased early compressive reducers such as WRDA®with HYCOLe or WRDAe-79,mid-
<br /> strengths. PolorSet does not contain calcium chloride range water reducers such as Daracem®-50 and 55,and
<br /> and is completely non-corrosive to reinforcing steel, thigh range water reducers such as WRDA°-I9 and
<br /> metal decks, and to all metal components of your Daracem®-100. Precaution should be taken to avoid mix-
