    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
