Precast Concrete Tunnel Segments

State-of-the-art technologies for high quality, durable concrete tunnel segments

This high-range water reducing admixture is based on the new generation of polycarboxylate technology that incorporates state-of-the-art molecular engineering to provide fast wet-out of powder materials. Benefits to concrete production are:

  • Rapid cement dispersion
  • Superior early and ultimate strengths
  • Increased productivity
