It accelerates cement hydration resulting in as DAREX II'', DARAVAIW and AIRALON-20 AEAO'; water <br /> shortened setting times and increased early compressive reducers such as WRDA°with HYCOL''or WRDA9-79,mid- <br /> strengths. PolarSet does not contain calcium chloride range water reducers such as Daracem"'-50 and 55,and <br /> and is completely non-corrosive to reinforcing steel, high range water reducers such as WRDAr' 19 and <br /> metal decks, and to all metal components of your Daracem`'-100. Precaution should be taken to avoid mix- <br /> admixture storage and dispensing system. It is formulat- ing PolarSet with other admixtures before they enter the <br /> ed to comply with ASTM C 494 Type C and can be used concrete.
