  • Applicable standards :
  • I. S: 9103 - 1999 ASTM C – 494 TYPE G
  • BS 5057 part - 3

Advantages

  • To impart high fluidity or workability to concrete, mortars and grouts which will maintain this property for longer periods

  • In the case of pumpable grouts high workability can be maintained for up to 4 hours.

USES

SIGMACHEME’S SUPERPLAST – R is ideal for uses with pumped cement or cement / sand grouts where either long feed lines have to be used, or the rate of injection is low.
