The company said the new finish mill enhances its ability to deliver consistent, high-performance cement.
Furno and Maschmeyer announce strategic agreement to produce cement using recycled concrete
18 December 2025US: Furno Materials has signed an agreement with ready-mix concrete producer Maschmeyer Concrete for the use of its compact modular cement kiln technology. Maschmeyer Concrete plans to operate the kilns using its 90,000t/yr of ‘waste’ concrete as a feedstock. The company will build an initial 50,000t/yr-capacity mini cement plant in Florida. The partners are currently conducting site analysis and a feasibility study for the project.
This latest deal brings Furno Materials’ total commitments to 295,000t/yr across announced and unannounced projects. The sale remains contingent on the successful deployment of its first commercial-scale reactor with concrete producer Ozinga in Chicago, Illinois.
Amrize commissions Ste. Genevieve plant expansion
17 December 2025US: Amrize has announced the commissioning of a production expansion at its cement plant in Ste. Genevieve, Missouri, increasing the plant’s capacity by 600,000t/yr to reach a total of 5.0Mt/yr. The expansion forms part of Amrize’s broader US$700m investment plan for 2025, aimed at strengthening operations and supporting domestic customers.
The company said that the project reinforces its commitment to ‘Made in America’ manufacturing, supporting local jobs and communities while ensuring high-quality cement supply for builders across the country.
Sublime Systems pauses Holyoke project after federal funding setback
11 December 2025US: Sublime Cement has announced a 10% workforce reduction and a pause in the development of its planned demonstration plant in Holyoke, Massachusetts, after the company failed to reverse a decision to cancel a US$86m federal grant, which would have funded 50% of the project. The company had been awarded the grant by the Department of Energy’s Office of Clean Energy Demonstrations (OCED), but the Trump administration cancelled all grants in May 2025. Sublime said that the loss of the grant disrupted the company’s financing plans and forced it to explore alternative scale-up options.
The company said in a statement “We are actively working through a robust set of alternative scale-up plans and have several exciting options to bring our first commercial plant online.”
Earlier in 2025, Microsoft committed to purchasing 623,000t of Sublime’s low-carbon cement to reduce the embodied emissions of its construction projects. The Holyoke plant was to supply the product, with a planned output of over 30,000t/yr. Sublime said that it remains in discussions with the Department of Energy.
US cement shipments up by 7% in July 2025
10 December 2025US: Total shipments of Portland and blended cement, including imports, reached an estimated 9.99Mt in July 2025, up by 7% from July 2024. Year-to-date shipments totalled 57.0Mt, down by 3% from the same period in 2024. Texas, Missouri, California, Florida and Alabama were the top cement-producing states. Texas, California, Florida, Ohio and North Carolina together accounted for 38% of total shipments.
Clinker production in July 2025 totalled 6.64Mt, nearly unchanged from July 2024. Cumulative clinker output for January to July 2025 fell by 7% year-on-year to 37.5Mt. Missouri, California, Texas, Florida and Alabama produced the most clinker.
US cement market increases import capacity as demand slows
28 November 2025US: Cement import capacity is continuing to rise despite a slowdown in demand and growing uncertainty over tariffs, according to a report by Argus Media. Cement supplier Ozinga initially expected demand would bounce back after the November 2024 presidential election. CEO Marty Ozinga said “Then the Liberation Day thing happened. I think that really put a pause to a lot of projects, just enough to make it very disappointing for most of the year,” referring to the tariffs rolled out in April 2025.
Tariffs have increased costs for importers by US$5-10/t, said On Field Investment Research managing partner Yassine Touahri. Market analyst Ed Sullivan forecasts cement consumption falling by 5% in 2025 and dropping by a further 0.2% in 2026, hitting a low of 100Mt. He said longer-term growth is still possible, citing a potential market size of 140Mt by 2050 if past per capita consumption rates return.
With mortgage rates above 6% and affordability at record lows, residential construction is expected to remain weak. Sullivan said that industry utilisation is running at 76%, below the 80% that producers ‘would like to see’, and he expects imports to hit a bottom at 17Mt in 2026, despite new import capacity coming online.
"On the import side, capacity additions are not slowing down at all", even though demand for additional imports is much less certain than it was three to five years ago, LEK Consulting managing director Olivier Asset said.
US: Heidelberg Materials has announced that it will acquire Walan Specialty Construction Products in Delaware under a binding purchase agreement. The transaction includes a 150,000t/yr capacity slag grinding plant with a vertical mill built in 2022 near the Port of Wilmington. The producer says that this acquisition will further strengthen its low-carbon cementitious portfolio and extend its market reach in the Northeast Region.
Cement product launch roundup, November 2025
19 November 2025Cementir Group launched two of its lower carbon cement products in the Middle East and Africa markets this week. We’ll take a look at this in more detail and cover other recent products news from cement producers.
Egypt-based Sinai White Cement will manufacture the products under Cementir’s D-Carb umbrella. One will be a Limestone Portland cement, to the CEM II/A-LL 52.5N specification EN197-1, with around a 10% clinker reduction. The other will be CEM II/B-LL 42.5N with around a 20% clinker reduction. Both of these reductions are in comparison to Aalborg White CEM I 52.5R. D-Carb is the name of Cementir’s product range for white low-carbon cements. It was launched in European markets in 2024, with II/ALL 52.5R cement, and then expanded to Asia Pacific regions, including Australia, in early 2025. Cementir says that its customers can switch to D-Carb from CEM I as it “integrates well with their production processes without requiring major formulation changes.”
In late October 2025 Dyckerhoff revealed that it was the first cement manufacturer in Germany to receive general building authority approval (abZ) for the use of CEM VI (SLL) cement in accordance with DIN EN 197-5. The German Institute for Building Technology (DIBt) granted approval for Dyckerhoff’s Lengerich cement plant. CEM VI is a newer type of composite cement similar to CEM II but with a lower clinker content. The SLL type that Dyckerhoff wants to make has a clinker content of 35 – 49 %, granulated blast furnace slag of 31 – 59% and limestone of 6 – 20%. The company says that this cement can be used in more than 60% of all concrete types produced in ready-mixed concrete plants. Its composition is also useful for low-carbon concretes when no fillers, such as fly ash, are available. Dyckerhoff added that the low hydration heat of the cement has a particularly positive effect in massive cast components.
Earlier in October 2025 Rohrdorfer held an inauguration ceremony for a new pilot unit for calcined (they say tempered) clays at its Rohrdorf cement plant. The pilot project started in July 2025 and has been processing up to 50t/day of raw clay. When Rohrdorfer launched the project in early 2024 it said that it was going to use waste heat from the main production line and was also considering the use of hydrogen to provide the remaining amount of heat required. Waste gases produced during calcination were also going to be fed back into the existing waste gas cleaning system of the clinker production line after leaving the pilot plant to further reduce emissions. Rohrdorfer said that its approach was going to be the first time waste heat recovery was going to be used in conjunction with calcining clay.
Meanwhile, in West Africa, Dangote Cement inaugurated its new 3Mt/yr cement plant near Abidjan in the Ivory Coast in mid-October 2024. Around the same time the company launched various products in the country, including its CEM I and CEM II brands 32.5R, 3X42.5N, 3X42.5R and 52.5N. This is a more traditional range of cement products compared to the ones above but note the highlighting of strength. This has been a key selling point for products in this part of the world previously, hence its focus. CEM II is a blended cement that uses lower levels of clinker. One clinker substitute in CEM II products is calcined clay. Gebr. Pfeiffer, for example, said in August 2025 that it was to supply a vertical roller mill to Ciments de Côte d'Ivoire (CIMCI) for clay grinding at its cement plant. There are also a number of other calcined clay projects in the Ivory Coast and other countries in West Africa. Further afield, JK Cement in India also started to market its LC3 clay calcined cement product line in October 2025.
Finally, US-based Amrize launched its ‘Made in America’ label for its cement range this week, “offering builders the guarantee of American manufacturing and quality, supporting American jobs and local communities.” Readers may recall that Amrize was recently owned by Switzerland-based Holcim. However, the company is currently keen to point out that its cement products are “made in the US from its raw materials and processing to manufacturing, meeting rigorous US performance standards.” Amrize does sell blended cements including FortiCem Portland-Pozzolan Blended Cement, ECOPlanet Cements and OneCem Portland Limestone Cement.
Most of the news stories highlighted above demonstrate a trend for blended cements with lower clinker factors. There’s no real change here. This has been happening for a long time and it is being driven by both profit and sustainability motives, although the current bunch of stories may also be turning up to coincide with the COP30 conference in Brazil. Note the inclusion of places outside of Europe and the drive for new blends. Another factor to consider here is protectionism in certain markets, as Amrize’s marketing drive suggests. New blends will also require new certifications, standards and approvals as is the case with Dyckerhoff’s work on CEM VI (SLL). The next trend to watch for will be the market reaction to carbon captured cements, such as Heidelberg Materials’ evoZero product. Will end users pay a premium for zero-carbon cements?
