    MasterPolyheed 3535

    Superplasticizer for the production of high quality backfilling grouts with exceptional workability retention for TBM

    Product description

    MasterPolyheed 3535 is a high performance admixture, mainly for use in the annular grouting behind the concrete lining of a Tunnel Boring Machine. At the start of the mixing process the presence of polymeric lateral chains, linked to the polymer backbone of the admixture, generate a steric hindrance which stabilises the hydraulic particles capacity to separate and disperse.

    Features and benefits

    • Production of grouts with low water cement ratios with excellent workability retention properties.
    • Improves the pumping property, especially with coarse, angular or poorly graded sands and aggregates
