Ecocem announced this week that it has achieved certification in the US for its ACT low-carbon cement technology. This follows CRH’s agreement to buy US-based Eco Material Technologies, a supplier of supplementary cementitious materials (SCM), which was revealed in late July 2025. These moves and others mark a flurry of activity by various companies in the US SCM sector in recent months.

Donal O’Riain, the founder and managing director of Ireland-based Ecocem, underlined the importance of certification in North America when he said that “The US is one of the largest cement markets in the world, and this certification will support integration into existing supply chains and offers a pathway for the sector to rapidly decarbonise.” The country imported just under a fifth, 19Mt, of its Portland and blended cement in 2024 according to the United States Geological Survey (USGS).

Ecocem started out as a manufacturer of cements made using ground granulated blast furnace slag (GGBS), a SCM, in the early 2000s. Its ACT technology was formally announced in 2022. It is described as a process that can make cements using “available fillers like limestone and local SCMs.” It is currently scheduled for a commercial launch in 2026, starting in France. In the US it is planning to build a terminal and mill at the Port of Los Angeles in California. This follows a previous attempt to build a slag grinding plant, also in California, in the 2010s.

CRH, another cement company with strong links to Ireland incidentally, said on 29 July 2025 that it had agreed to acquire Eco Material for US$2.1bn. The latter operates a network of fly ash, pozzolan, synthetic gypsum and green cement operations. It partners with electricity generators to process about 7Mt/yr of fly ash and 3Mt/yr of synthetic gypsum and other materials. As CRH’s CEO Jim Mintern put it, “this transaction secures the long-term supply of critical materials for future growth and puts CRH at the forefront of the transition to next generation cement and concrete.” The deal is expected to close by the end of 2025. In separate comments to analysts Mintern added that he expects the market for SCMs to double in the US by 2050.

Other players have also been busy in recent months. Amrize, for example, noted in its financial results for the second quarter of 2025 that it had broken ground on a new fly ash beneficiation facility in Virginia in the reporting period. Last week, Graymont and Fortera signed an agreement to produce Fortera’s ReAct low-carbon cement product by using Graymont’s existing lime production operations. Fortera runs a plant in Redding, California that takes captured CO₂ from the adjacent CalPortland cement plant and uses it to manufacture its own proprietary SCM. Back in April 2025 Buzzi Unicem said that it had partnered with Queens Carbon to produce a novel cement and SCM. The start-up was intending to build a 2000t/yr demonstration plant at Buzzi Unicem’s cement plant in Stockertown, Pennsylvania.

The backdrop to all of this attention on SCMs in the US are the cost of cement and sustainability. Using more SCMs reduces clinker usage in cement and it can reduce the cost. At the same time reducing the amount of clinker used decreases the amount of CO₂ emissions. So, for example, Ecocem says that its ACT technology can reduce CO₂ emissions by up to 70% compared to conventional cement.

A report by Mckinsey on SCMs in the autumn of 2024 reckoned that growth in the cement market in North America was expected to be ‘robust’ in the next 15 years to 2050. However, the sector faces material, particularly clinker, and labour shortages. Enter SCMs! It went on to assert that much of the available stocks of GGBS and fly ash in the country are effectively used. Yet, traditional industrial SCMs such as GGBS, fly ash and limestone are anticipated to be available for longer than in Europe as industries such as steel manufacture and electricity generation will take longer to decarbonise. Hence companies such as Ecocem are preparing to import them, ones like CRH are cornering existing stocks and others such as Fortera and Queens Carbon are working on creating their own ‘virgin’ sources. At the same time the American Cement Association has been promoting the use of Portland Limestone Cement in the country.

All this helps to explain the interest in SCMs in the US right now. It’s a busy moment.

Ivory Coast: Gebr. Pfeiffer will supply an MVR 3070 R-2 vertical roller mill to Ciments de Côte d'Ivoire (CIMCI) for clay grinding at its cement plant. The mill will produce 62t/hr of clay at ≤10% R 0.090mm for use in calcined clay cement. The order was placed by China-based contractor CBMI, which is managing the engineering, procurement and construction contract and will also supply the suspension calcination plant. The mill is scheduled to begin operation at the end of 2026.

Fiji: Fijian Holdings subsidiary Pacific Cement (PCL) has resumed cement production following the completion of commissioning works on its repaired mill, according to the Fiji Times. Fijian Holdings deputy chair Sakiusa Raivoce said supply of bulk and bagged cement had normalised.

Production had halted in March 2025 due to a mill breakdown. Raivoce said PCL is now fast-tracking an upgrade of the existing mill to reduce future risks and improve reliability. Persistent failures in recent years had resulted in a reliance on cement imports to satisfy local demand.

Honduras: Cementos del Norte has inaugurated its new Mill No. 4 at the Río Bijao plant in Choloma, Cortés, according to a social media post by the producer. The new unit adds 140t/hr of cement production capacity, raising the plant’s total capacity to 7000t/day.

India: UltraTech Cement has commissioned its second cement grinding mill at the Maihar unit in Madhya Pradesh, adding 1.8Mt/yr to its domestic production capacity. The first mill at the site began operations in March 2025.

The expansion raises UltraTech’s total grey cement capacity in India to 186.86Mt/yr and 192.26Mt/yr globally. The company said the move forms ‘part of its larger strategy.’

Türkiye: Oyak Cement will convert Mill 3 at its Darıca integrated cement plant to a slag grinding unit, according to local press reports.

The company has submitted the project to the government and the environmental impact assessment process has reportedly begun. The US$252,000 investment will add 14 jobs. The modified facility will grind 1200t/day (360,000t/yr) of slag, along with 18,000t of limestone in its other mills.

Brazil: Votorantim Cimentos has received and begun installing a new cement mill at its Salto de Pirapora plant near São Paulo as part of its US$878m national expansion programme.

The 210t mill took six months to arrive from China via ship, and was then transported by a truck convoy from the Port of Santos to the plant. The mill will increase the plant’s capacity by 1Mt/yr. The unit is part of the Salto-Santa Helena complex, which will see its capacity grow by 20% when the expansion completes in the second half of 2025. Construction began in the first half of 2024.

General manager Rafael Frederico said “We are celebrating a new phase in the expansion project of the Salto de Pirapora plant with the arrival of the mill and all the equipment for assembling the new mill. The operation to transport the equipment from China to our unit was complex and executed with great operational excellence by our multidisciplinary teams and partners.”

Fiji: The Fijian Competition and Consumer Commission (FCCC) has assured the public that there should be no shortage of cement despite the temporary suspension of operations at Pacific Cement. CEO Senikavika Jiuta said FCCC is working closely with suppliers and monitoring the supply chain to prevent unfair practices.

Pacific Cement suspended operations on 21 March 2025 after its mill sustained mechanical damage. Repairs are underway and expected to finish by 27 May 2025. FCCC engaged with both Pacific Cement and Tengy Cement to conduct a market study, concluding that Tengy Cement’s increased production at its Suva and Lautoka plants will meet demand until Pacific Cement resumes full operations.

India: Gebr. Pfeiffer has commissioned a Pfeiffer MVR 6000 R-6 raw material mill and a Pfeiffer MPS 3550 BK coal mill at UltraTech Cement’s Maihar cement plant in Madhya Pradesh. The Germany-based company said that these were the 42nd and 43rd vertical roller mills supplied to UltraTech Cement.

Chile: FLSmidth has inaugurated a new manufacturing plant for mill liners and related products in Casablanca. The Denmark-based company has invested €21m in the 11,250m² unit. It has a capacity of 6500t/yr of coatings. FLSmidth said that LEED-certified mill liner manufacturing facility reduces carbon emissions by up to 56% in the manufacturing process and recycles and reuses all water used during the manufacturing process as well. The site will also create up to 250 new jobs in the Valparaìso region

Mikko Keto, CEO of FLSmidth commented, “Our new Casablanca mill liner manufacturing facility, which joins FLSmidth’s extensive service network in Chile, is much more than manufacturing infrastructure - it is a statement of our commitment to responsible mining, our mill lining portfolio and the communities of South America."

FLSmidth said in early 2024 that it was planning to sell its cement equipment division, FLSmidth Cement. This decision was made so the company could focus on its mining business.
