Denmark: Finland-based Betolar has supplied its Geoprime additive for its maiden construction project in Denmark. Its customer IBF used the additive to produce low-cement paving stones for a 1.5 hectare expansion to the lorry park at the Port of Aalborg. The stones consisted of an 84mm-thick cement-free base made of Geoprime material, with a 6mm-thick cement-based concrete top. The supplier said that the use of Geoprime reduced the project's cement consumption by 90%. This more than halved the carbon footprint of the work.

Betolar's chief commercial officer Ville Voipio said "This shows that the circular economy solution we have developed, which utilises industrial side streams, also works in large construction projects. We have been doing development work with IBF for a long time. Now there is a product on the Danish market that radically cuts emissions compared to traditional products."

Denmark is committed to eliminating 70% of its annual CO₂ emissions between 2020 and 2030.

Denmark/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."

Denmark: Switzerland-based Holcim has made an investment in 3D concrete printer supplier COBOD International. Holcim hopes that the investment will help it to further expand its TectorPrint 3D printing ink range. Holcim and COBOD International's collaboration dates to 2019, since which time the partners have 3D printed windmill tower bases in Denmark, a school in Malawi and a housing development in Kenya.

Holcim's head of global research and development, Edelio Bermejo, said “At Holcim, we are continuously expanding our range of building solutions to build better with less, working to improve living standards for all in a sustainable way. 3D concrete printing will help us meet these goals."
