Sika® Plastocrete®-909

Mid-range Water Reducing Concrete Admixture

Plastocrete® -909 is a mid-range water reducing for concrete. It is concentrated solution based on Synthetic Polymer and Modified Lignosulphonate. Effective water reduction provides substantially improvement on strength either cement saving or concrete with fly ash up to 30% replacement.

Plastocrete® -909 provided the following properties :
  • Water reduction up to 18% against control mix
  • High PFA replacement up to 30%
  • Equal strength to control mix with less cement
  • High early strength
  • Compensates for slow early strength gain achieved by cement replacements (PFA, GGBFS)
  • Increased workability with lower dosages
  • Excellent slump retention
