MasterPolyheed 3535 - Superplasticizer for the production of high quality backfilling grouts with exceptional workability retention for TBM tunnels 

What is MasterPolyheed 3535 used for?

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.
