Master Builders Solutions to supply 11,000t of concrete admixtures for Fehmarnbelt Tunnel project
03 July 2023Denmark/Germany: US-based Master Builders Solutions has won a contract to supply admixtures for use in the Fehmarnbelt Tunnel project. The project will build a 17.6km immersed tunnel between the islands of Fehmarn in Germany and Lolland in Denmark. It will directly connect Germany via a double-track railway and four-lane motorway to eastern Denmark and the Scandinavian Peninsula beyond. This will reduce rail travel time between Hamburg in Germany and Copenhagen in Denmark by 35% to 3 hours 15 minutes. The tunnel will consist of 79 standard 217m-long precast elements, and a further ten 85.7m-long service elements. The latter include a subfloor sections in addition to the tunnel's four tubes. Master Builders Solutions says that it will supply 11,000t of admixture to produce a total 3Mm3 of concrete required for the project. The supplier said that its admixtures will help concrete to meet specifications in line with the Fehmarnbelt Tunnel's projected 120-year lifespan. Master Builders Solutions has collaborated with contractor FLC to develop a new MasterEase superplasticiser for use in the project.
Master Builders Solutions Denmark technical manager Jens Qvist said "This has been an incredibly exciting process, requiring very close collaboration with both our own European colleagues and FLC’s Danish and international concrete experts."
