Superplast AF is a Chloride free Accelerating and Frost preventing admixture, used to promote rapid setting of concrete and mortar in very low and minus temperature, conforming to to IS: 9103:1 999 (Reaffirmed 2004) Edition 2.2 (2007-08).Advantage: Works as a freezing point depressant for the mixing water. Makes the fresh mass more frost resistant. Faster setting time generates very high early strength in concrete. Reduce time of plaster and finishing. Lower maximum temperature of concrete. Negligible effect on initial strength. Increase ultimate strength.
