Argentina: Holcim Argentina has launched a new line of liquid additives under the brand Tector. The line encompasses two products: Tector Hydrophobic 1230 reduces permeability in cementitious mortars, improving workability and corrosion resistance, while Tector Latex 1700 enhances adhesion, flexibility and plasticity in various applications, reducing surface cracking and flaking.

China: Switzerland-based Sika has opened its new Suzhou Technology Centre in Jiangsu Province. The centre will help Sika to develop its sustainable and high-performance technologies in order to grow it market potential throughout the Asia/Pacific region. By strategically expanding its research and development activities across all core technologies, Sika aims to further strengthen its global innovation leadership.

Chief innovation and sustainability officer Patricia Heidtman said "With our new technology centre, we are strengthening our innovation capabilities in the Asia/Pacific region and are fostering synergies in sustainable construction and environmentally friendly mobility. We have created the ideal framework for close collaboration between our research teams. It will thus enable us to develop forward-looking technologies for our customers that combine sustainability with performance."

Ireland/UK: UK-based construction chemicals company Oscrete has raised its stake in its Northern Ireland-based distributor, Adcrete, to 90%. The group says that this will enlarge its customer base across Ireland in line with its 2024 strategic growth plan.

Director Scott Wilson said “The strengthened Oscrete business model and presence in Ireland will ensure the team has the infrastructure and the expertise to become the leading supplier of concrete admixtures and additives in the country.” He added “Our growth and turnover in Ireland has increased by 200% in the last four years and this growth serves to support the wider business operations.”

India: Finland-based Betolar introduced its artificial intelligence-based service for production of reduced-CO₂ concrete using its Geoprime additive at World of Concrete India 2023 on 18 October 2023. Betolar designs recipes and provides a liquid chemical dosing system and post-production services to Geoprime users. Dow Jones Institutional News reports that Betolar has concluded strategic tie-ups in South and West India, and is ‘actively planning’ further expansion.

Managing director Abhishek Bhattacharya said "Interest in our solution is growing fast in India and we have successfully demonstrated that the twin goal of sustainability and performance can be achieved remarkably faster with Betolar’s Geoprime solution.”

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."

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:

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.”

India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.

Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."

India: Three new Indian concrete companies have separately secured agreements for the use of Finland-based Betolar’s Geoprime alkali-activated slag and fly ash additive. Reuters News has reported that the companies are Balaiji Cement Products, Shiv Tiles and SNEH Precast. Engineering company Godrej & Boyce has also signed a letter of intent with the supplier for pilot production of concrete blocks, paving slabs and other elements.

Betolar expects producers to achieve global concrete production volumes of 250,000t/yr of concrete containing Geoprime by 2023.

Finland: Betolar has signed a letter of intent with Australia-based RISAB and the Vanadium Recovery Project to research the use of steel slag from which vanadium has been extracted in concrete production. Dow Jones Institutional News has reported that the company says that, through it Geoprime alkali-activated additive technology, the new slag source could replace 10% of the cement used in concrete production in Finland.

CEO Matti Löppönen said "We see a huge opportunity for Betolar here. If successful, we would be able to offer our customers a specific, currently unused slag of the steel industry to replace cement in concrete. Our customers already have experience in utilising other types of slag in the production of concrete using Geoprime. Utilising new side streams will expand the reach of our solution as planned.”

Betolar launched Geoprime in September 2021. It is currently developing a recipe-optimising artificial intelligence (AI) and data platform to bring together concrete producers and suppliers of slag, ash and other materials.
