France: Lafarge France is participating in a 76-unit housing development project called Recygénie, at Gennevilliers in Hauts-de-Seine. Lafarge France will supply the project with 100% recycled concrete for use in facades, interior walls and roof slabs. It produced 2000t of 100% recycled 'clinker' at its Altkirch cement plant in Haut-Rhin during a suspension of ordinary clinker production in 2022. It has produced 1600m3 of recycled concrete to date. The concrete won the New Materials Prize at L'Usine Nouvelle's Sustainable Industry Awards 2023.

The Recygénie housing project is due for delivery in late 2024.

Philippines: Holcim Philippines and Sungshin Cement have signed a memorandum of understanding whereby Holcim Philippines will be priority supplier of cement for use in Sungshin Cement's ready-mix concrete operations in the Philippines, InPR News has reported. South Korea-based Sungshin Cement is anticipating growing demand from infrastructure projects, partly due to a US$3bn development loan agreement between the government of the Philippines and South Korea.

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."

World: The Global Cement and Concrete Association (GCCA) has named the 15 anticipated deliverers of low-CO2 cement and concrete production shortlisted for participation in its second Innovandi Open Challenge. The association chose the start-ups based on their potential to deliver CO2 emissions reduction in the global cement and concrete sector in line with its Concrete Future 2050 Net Zero Roadmap. The applicants are presenting their pitches to GCCA members on 30 June 2023. All those accepted will gain access to members' plants, labs, networks and expertise. The following start-ups made the Innovandi Open Challenge 2023 shortlist:

 

Arrakis Materials US Carbon negative materials for concrete
Chement US Room temperature cement production
EcoAdmix Global UK Nanotechnology ('HDT') for concrete
EcoLocked Germany Biocarbon-based admixtures
EnviCore Canada Low temperature supplementary cementitious material production
Enzymatic US Carbon negative enzymatic concrete corrosion inhibition and recycling
Louis Structures US Municipal solid waste-based lightweight aggregates
MEP - SeaMix US Basalt fibre and graphene-based admixture
Nano Crete US Graphene-enhanced CO2 sequestration
Nanospan India India Graphene-based admixture
NeoCrete New Zealand Nano-activator for natural pozzolans
Queens Carbon US ~500°C cementitious materials production
The Cool Corporation UK Carbon negative carbon nanotube-based additive for concrete
Ultra High Materials US Clinkerless cement
Versarien Graphene UK Graphene-based admixture ('Cementene')

GCCA cement director and innovation lead Claude Loréa said “We received more than 70 quality applications, so drawing up a shortlist was challenging." Loréa continued "Our essential industry needs something easily scalable and affordable. Those start-ups on the list demonstrated the most potential, and we look forward to hearing more about their ideas. But we’ll also be keeping in touch with other start-ups who didn’t make this year’s shortlist, with future projects in mind.”
