Precast concrete
Probably the most important consideration when using Super-Pozz® is its ability to decrease the water demand of concrete mix without effecting the workability characteristics. For equal workability therefore, the water reduction contributed by Super-Pozz® will lower the water/cement ratio and as a result improved strength gains and durability. This is important for precast concrete, where high strengths are required at early ages in order to increase mould turnover and reduce handling damage.

The main features with the use of Super-Pozz® in Precast concrete units can be summarized as follows:

  • Reduced water demand
  • Use of more cost-effective admixture dosages
  • High early strengths; resulting from lower w/c ratio
  • Improved ultimate strengths
  • Improved durability
  • Good surface finish
  • Reduced shrinkage
