MasterPolyheed 8830 - New generation mid-range water reducer


How does MasterPolyheed 8830 work?

MasterPolyheed 8830 is a multi-component, non-chloride, mid-range water reducing admixture designed to improve the performance of concrete both in the plastic and hardened states. It is added at the batch plant after 75% of water has been added to the mix.

Recommended uses:

  • All types of concrete where a non-chloride water reducing admixture is required, especially in the slump band (80 -150mm)
  • Improving the performance of pumped concrete, shotcrete and conventionally placed concrete
  • Improving the performance of plain, reinforced, precast, light weight or standard weight concrete
  • Use in white or coloured concrete
  • Use in architectural concrete, especially where off-form and/or surface finish is critical
  • Use in concrete containing harsh aggregates and/or manufactured sand


What makes MasterPolyheed 8830 unique solution?

Non-chloride water reducing admixture enables mid-range concrete slump of 80-150mm.


What are the benefits of MasterPolyheed 8830?

In the plastic state:

  • normal setting characteristics throughout the recommended dose range
  • reduced segregation, particularly in lean mixes and mid slump concrete
  • improved mix rheology
  • improved pumpability
  • reduced water content for a given workability
  • enhanced finishability, especially for concrete with manufactured or harsh aggregates

In the hardened concrete:

  • no added chlorides, conforms to the most stringent chloride ion limits including AS3600 concrete structures code, will not initiate or promote the corrosion of reinforcing steel
  • increased strength – compressive, flexural and bond (concrete to steel)
  • superior finished appearance
  • increased density and durability
  • reduced permeability – improved watertightness
  • reduced cracking
