Description

ADVA® CAST 640 is a polycarboxylic high range water reducing admixture. ADVA® CAST 640 contains no added chlorides and no TEA.

ADVA® CAST 640 is specially designed for producing superior high early strength concrete in precast applications. ADVA® CAST 640 complies with AS 1478, Type HWR.

Application areas

  • Concrete for precast structural elements with high early strength
  • Low water-cement ratios concrete in low to high placement slump ranges

Benefits

  • Superior early strength enhancement, accelerates cement hydration with efficient dispersion effect 
  • Slump retention to place concrete in large precast units/high temperature regions
  • High workability for faster placement and improved mix consolidation
  • Exhibits superior water reduction and superior surface finish without stickiness, tearing / spotty set features
  • Optimises precast concrete production to remove the need for heat curing

Packaging

  • 205 L Drum
  • IBC 1000L
  • Bulk
  • Pail
